SAFIRE should be utilized to its full potential, as this innovative image reconstruction algorithm can significantly reduce image noise without loss of sharpness, preserving image quality and anatomical information. This is particularly important in the case of non-hemorrhagic stroke, where image noise can obscure small lesions, potentially leading to misdiagnosis and inappropriate treatment. SAFIRE has five variations of strength, making it essential to identify the most optimal SAFIRE Strength for head CT Scan examinations in non-hemorrhagic stroke cases. The aim of this study is to determine differences in image quality and anatomical information in head CT Scan of non-hemorrhagic stroke cases using SAFIRE variations to identify the most optimal SAFIRE Strength. This experimental quantitative study involved a sample of 30 patients, with each case reconstructed using five SAFIRE Strength variations. Image quality was assessed using the IndoQCT application, while anatomical information was evaluated through the visual grading analysis method by three radiologists. Image quality data were analyzed using the Friedman statistical test, which resulted in a p-value of 0.000 (p < 0.05), indicating significant differences among the SAFIRE Strength variations. Similarly, anatomical information data were analyzed using the Kruskal-Wallis statistical test, yielding a p-value of 0.000 (p < 0.05), confirming significant differences across the variations. The results of the study showed that there are significant differences in image quality and anatomical information among the five SAFIRE Strength variations. SAFIRE Strength 3 was identified as the most optimal for head CT Scan examinations in non-hemorrhagic stroke cases, as it produces images with minimal noise and higher detail, providing clearer anatomical information compared to the other SAFIRE Strength variations.

Magnetic Resonance Imaging (MRI) Brain examinations often encounter uncooperative patients, necessitating rapid scanning techniques that yield optimal results. To address this challenge, advanced technologies such as deep learning can be leveraged to accelerate scan time, reduce noise, and enhance image precision. This study aims to evaluate the disparity in MRI Brain image quality with and without deep learning in tumor cases to achieve superior diagnostic imaging. Employing a quantitative experimental approach, this research analyzed a sample of 30 patients collected from January to February 2025. Three Radiologist Specialists assessed the images using a questionnaire based on the Visual Grading Analysis (VGA) method. The obtained responses were statistically examined through Cohen’s Kappa consistency test and Wilcoxon Signed-Rank Test. Findings revealed a statistically significant difference in image information between deep learning-assisted and conventional MRI scans. In T2 TSE sequences, deep learning reconstruction demonstrated superior anatomical visualization of the Gray Matter, White Matter, Lateral Ventricles, Basal Ganglia, and Parafalx Cerebri. However, in brain tumor pathology visualization, conventional MRI exhibited sharper and more distinct tumor delineation. Although deep learning-enhanced T2 TSE sequences reduced scan duration and improved overall image quality, they provided suboptimal diagnostic information in tumor cases.

Examinations performed on MRI of cervical vertebrae take a long time and cause patients to feel uncomfortable during the examination. FSE is a technique that can be used to produce fast examination times. Patient discomfort can also cause movement during the examination, which can cause artifacts in the resulting images. These movements can be minimized with the PROPELLER technique. This study is quantitative using an experimental method with a sample size of 15 volunteers who were each scanned with T2 FSE and T2 PROPELLER sequences. This study was conducted using a questionnaire in which each image produced was evaluated by 2 radiology specialist observers using the visual grading analysis (VGA) method to assess each anatomy of the corpus vertebrae, intervertebrae disc, spinal cord, CSF, intraforamen structure, nerve root and artifacts. The statistical results showed that the image quality of T2 FSE and T2 PROPELLER sequences had ap value of 0.000 (p<0.05). The sequence has a difference, namely T2 PROPELLER produces more detailed image quality on anatomy and pathology, and can reduce the occurrence of artifacts due to movement in the cervical area, and T2 FSE produces less informative image quality due to artifacts. In addition, there are differences in MRI scanning time of cervical vertebrae T2 FSE sequences which are faster than T2 PROPELLER and T2 PROPELLER is good at reducing artifacts.

Due to the long scan time, patients often report pain and discomfort during lumbar MRI examination. NEX and SENSE are two parallel imaging parameters that affect scan time. However, the resulting image information is also affected by NEX and SENSE. Therefore, this study examines the information between NEX variations with and without SENSE on anatomical images and their relationship with scan time on lumbar T2 TSE MRI examinations. This study is quantitative and uses an experimental method. The sample in this study was 10 volunteers who would be given 6 treatments, namely NEX 1 variation without SENSE, NEX 1 with SENSE, NEX 2 without SENSE, NEX 2 with SENSE, NEX 3 without SENSE, and NEX 3 with SENSE on Lumbar T2 TSE MRI examinations in January 2025. Using the Visual Grading Analysis (VGA) method, two radiology specialist observers analyzed the image results. Then the Cohen's Kappa consistency test was carried out and the Friedman test was used to verify the questionnaire results statistically. This study shows that there is a significant difference in the value of image information between NEX 1 variations of vertebral body anatomy with and without SENSE. While in the anatomy of the Intervertebral Disc, Ligament, Spinal Cord, and Spinal Stenosis did not show a significant difference in each variation of NEX with and without SENSE. For scan time, with NEX variations using SENSE requires a shorter scan time compared to without the use of SENSE.

MRI examination of the manus has a challenge in obtaining optimal image quality. Good image quality depends on four characteristics, one of which is the Signal to Noise Ratio (SNR). SNR can be affected by the use of appropriate radiofrequency (RF) coils so that it can increase the SNR value. This study aims to analyze the impact of using different coils on SNR and CNR values, especially in sagittal sections of Proton Density Fat Sat scans. This study is a quantitative study using 10 volunteer samples in the period of February 2025. The results of the study show that the SNR value in the overall anatomy has a p-value <0.05 which means there is a significant difference using flexible coils and special purpose coils. While the SNR value in per-anatomy manus digits 2-3 has a significant difference except for the volar plate anatomy with a p-value = 0.121 meaning there is no significant difference. And compared to flexible coil, the use of special purpose coil in this study has a higher CNR value, especially in the anatomy of the Distal Interphalangeal Joint - Middle Phalanges with an average value of 1221.200. This study provides evidence that the selection of the right coil greatly affects the quality of the resulting image, and the use of special purpose coil is considered to produce better image quality. Therefore, the author recommends the use of special purpose coils in MRI examinations of the manus digits 2-3.

MRCP is a non-invasive imaging method used to visualize the biliary system and detect abnormalities in the bile ducts or gall bladder. In taking images, there are two techniques, namely the mouth breath hold (MBH) technique and the trigger technique, where the MBH technique is carried out by the radiographer giving instructions directly related to the patient's respiratory movements, while the trigger technique uses respiratory gating to detect breathing patterns and minimize image blur due to organ movement. At Department of Radiology SMC Telogorejo Semarang both techniques are used in MRCP examinations by looking at the condition of each patient. So the author is interested in comparing the results of anatomical information from the two techniques. Methods: This research uses a quantitative design with an experimental approach. Data was collected from 10 patients who underwent MRCP examinations at the Department of Radiology SMC Telogorejo Semarang in August–September 2024. The scanning procedure was carried out using a T2 HASTE coronal section sequence twice for each patient using the MBH and trigger technique. Anatomical information was assessed by means of visual grading analysis by 3 radiologists on the structure of the cystic duct, intra-hepatic duct, common hepatic duct, common bile duct, pancreatic duct, and gallbladder (gallbladder) using a questionnaire with a scale (1–4). Then the data was analyzed using SPSS to determine whether there were differences in image information from the two techniques using the Wilcoxon difference test. This research has passed the ethical test number: KEPK/UMP/170/I2025. Results: Based on the results of the Wilcoxon test, both for the entire anatomy and for each anatomy, it shows a p-value < 0.05. This indicates that there are significant differences in the anatomical information produced by the two techniques. Based on the mean rank value, the most optimal technique for displaying anatomical information is MBH. This advantage is due to its ability to reduce movement artifacts through the breath-hold method, resulting in clearer and more detailed anatomical images compared to the trigger technique. The MBH technique is more effective in improving MRCP anatomical information, especially in patients with respiratory instability. It is hoped that these results can be a reference in determining the optimal method for MRCP examination.

Fat suppression merupakan teknik penting dalam pencitraan MRI, khususnya untuk meningkatkan visualisasi struktur anatomi dengan mengurangi sinyal lemak. Penelitian ini bertujuan untuk mengevaluasi perbedaan kualitas citra pada pemeriksaan MRI Cervical pada penggunaan tiga teknik fat suppression pada masing-masing sekuen, yaitu T2 TSE Dixon, T2 TSE SPAIR, dan T2 TSE STIR. Evaluasi dilakukan pada struktur anatomi CerebroSpinal Fluid (CSF), Spinal Cord, Discus dan Bone Marrow dengan parameter kualitas citra berupa Signal-to-Noise Ratio (SNR) dan Contrast-to-Noise Ratio (CNR). Hasil analisis statistik menunjukkan bahwa terdapat perbedaan yang signifikan pada nilai SNR pada penggunaan ketiga teknik fat suppresion pada masing-masing sekuen. T2 TSE STIR memiliki mean rank tertinggi, diikuti oleh T2 TSE Dixon dan T2 TSE SPAIR. Sebaliknya, tidak ditemukan perbedaan yang signifikan pada nilai CNR antar ketiga teknik. Meskipun nilai SNR tertinggi diperoleh dari sekuen T2 TSE STIR, bukan berarti teknik tersebut memiliki kualitas citra yang paling optimal. Faktor lain seperti karakteristik jaringan dan sensitivitas masing-masing teknik terhadap inhomogenitas medan magnet turut memengaruhi hasil pencitraan. Setiap teknik menunjukkan performa yang bervariasi tergantung pada jenis jaringan yang dianalisis, sehingga pemilihan teknik fat suppression sebaiknya disesuaikan dengan kebutuhan diagnostik yang spesifik.

Penelitian ini bertujuan untuk menganalisis perbedaan informasi citra pada pemeriksaan MRI lumbal menggunakan sekuens T2 FSE potongan sagital dengan teknik Autocalibrating Reconstruction for Cartesian Imaging (ARC) berdasarkan variasi nilai Time Repetition (TR) pada kasus Hernia Nukleus Pulposus (HNP). Metode penelitian yang digunakan adalah kuantitatif eksperimental dengan sampel sebanyak 10 pasien yang menjalani pemeriksaan MRI lumbal dengan tiga variasi nilai TR, 3000 ms, 3500 ms, dan 4000 ms. Penilaian informasi anatomi dilakukan oleh dua dokter radiologi menggunakan kuesioner, dan data dianalisis menggunakan uji friedman. Hasil penelitian menunjukkan adanya perbedaan yang signifikan (p < 0,05) antara variasi TR terhadap informasi citra, dengan nilai TR 4000 ms memberikan mean rank tertinggi (2,27), diikuti TR 3500 ms (2,03) dan TR 3000 ms (1,71). Perbedaan signifikan ditemukan terutama pada anatomi medula spinalis dan discus intervertebralis, sementara struktur lain seperti corpus vertebra, cairan cerebrospinal fluid (CSF), ligamentum flafum,dan ligamentum posterior tidak menunjukkan perbedaan berarti. Peningkatan nilai TR terbukti meningkatkan rasio sinyal terhadap noise (SNR), yang berdampak pada peningkatan kualitas informasi anatomi. Dengan demikian, nilai TR 4000 ms direkomendasikan sebagai parameter optimal untuk memperoleh kualitas citra dan informasi anatomi terbaik pada pemeriksaan MRI lumbal sekuen T2 FSE menggunakan teknik ARC.

Herniasi Nukleus Pulposus (HNP) merupakan salah satu penyebab utama nyeri pinggang yang sering dijumpai pada populasi usia produktif, khususnya antara 30 hingga 50 tahun, dengan puncak kejadian pada usia 40–45 tahun. Kondisi ini terjadi akibat penonjolan nucleus pulposus melalui annulus fibrosus discus intervertebralis, yang dapat menekan saraf dan menimbulkan nyeri. Pemeriksaan MRI menjadi modalitas utama dalam mendiagnosis HNP karena kemampuannya dalam menampilkan jaringan lunak secara detail, terutama dengan teknik fat suppression yang berfungsi untuk menekan sinyal lemak agar visualisasi struktur anatomi menjadi lebih jelas. Penelitian ini bertujuan untuk membandingkan kualitas citra antara sekuen T2 TSE Fat Saturation mode weak dan strong pada MRI lumbal pasien HNP. Menggunakan pendekatan kuantitatif terhadap 10 pasien di RS SMC Telogorejo Semarang, penilaian dilakukan oleh dua dokter spesialis radiologi melalui metode visual grading analysis. Hasil uji Wilcoxon Signed Test menunjukkan bahwa T2 Fat Sat mode strong memberikan kualitas citra yang lebih baik secara signifikan pada struktur discus intervertebralis, medulla spinalis, CSF, spinal cord dengan nilai p < 0,05 yang menunjukan terdapat perbedaan yang signifikan. Sedangkan pada corpus vertebrae, ligamentum flafum dan ligamentum posterior tidak terdapat perbedaan yang signifikan. Dengan mean rank lebih tinggi pada mode strong (17,69) dibandingkan weak (15,50) dan nilai p < 0,001 secara keseluruhan, disimpulkan bahwa sekuen T2 Fat Sat mode strong lebih efektif dalam menghasilkan informasi anatomi yang optimal pada pemeriksaan MRI lumbal kasus Hernia Nukleus Pulposus.

Background: Conventional ultrasound (USG) gel was generally based on carbomer 940, which was relatively expensive, difficult to access in some areas, and not environmentally friendly due to its non-biodegradable nature. This study aims to evaluate the potential of salacca leaf sap as an alternative material for a more affordable, easily obtainable, and environmentally friendly natural ultrasound gel.Methods: A quantitative experimental study was conducted on 30 adult patients. Each subject underwent two liver ultrasound examinations using carbomer 940 gel and gel from salacca leaf sap. Image assessment was conducted by three radiology specialists using the visual grading method on the parameters of parenchyma, portal vein, nodules, and artifacts. Data were analyzed using the Wilcoxon test and Cohen's Kappa test to measure inter-rater agreement.Results: The research results indicate that there is no statistically significant difference between the ultrasound images using factory gel and salacca leaf sap gel (p 0.05). All image parameters, such as parenchymal homogeneity, visualization of the portal vein, and minimal artifacts, appeared equivalent in both types of gel.Conclusions: Salacca leaf sap shows physical characteristics that support ultrasonic wave transmission and is capable of producing liver ultrasound images comparable to commercial gel. With local availability, low cost, and environmentally friendly properties, this material has the potential to be a viable alternative to ultrasound gel that can be further developed for clinical practice and areas with limited access.
