Abstract

Ejeksi Fraksi (EF) merupakan parameter untuk menilai kemampuan jantung dalam memompa darah ke seluruh tubuh. Saat ini modalitas yang sering digunakan untuk mendeteksi nilai EF adalah USG, tetapi memiliki keterbatasan yaitu poor acoustic window atau kualitas gambaran kurang optimal dan tergantung kemampuan teknologis. Ahli MRI Bellenger dan Friedrich menyatakan bahwa pemeriksaan Cardiac Magnetic Resonance memiliki keunggulan dalam memberikan akurasi nilai EF dan memiliki 2 metode pengukuran View Short Axis dan Long Axis. Tujuan:i untuk mengetahui akurasi nilai ejeksi fraksi ventrikel kiri pada pemeriksaan Cardiac Magnetic Resonance dengan metode view short axis dan long axis terhadap echocardiography. Metode: desain penelitian deskriptif kuantitatif tentang perhitungan EF dan dilakukan di instalasi radiologi rumah sakit di Jakarta pada bulan Juli–Oktober 2022 dengan sampel 33 pasien. Data diperoleh dengan cara observasi dan pengukuran menggunakan software CVI 42 yang terdapat pada perangkat MRI 1,5T Merk GE Signa Voyager. Data dianalisis menggunakan perangkat lunak Microsoft Excel dan SPSS untuk menghitung rata-rata EF dan selisih rata-rata EC-SA serta EC-LA terhadap hasil echocardiography. Hasil: Nilai rata-rata presentase EF pada metode pengukuran LVEF-EC sebesar 41%, LVEF-SA sebesar 40% dan LVEF-LA sebesar 43%. Ketepatan nilai fraksi ejeksi didapatkan nilai rata-rata selisih EC-SA sebesar 0,939 dengan presentase 3% dan nilai rata-rata selisih EC-LA sebesar 1,812 dengan presentase 5%. Simpulan: Hasil pengukuran perhitungan ejeksi fraksi dengan metode short axis lebih akurat di bandingkan long axis sehingga dapat dijadikan standar prosedur pemeriksaan Cardiac Magnetic Resonance. Standar ini akan memberikan kualitas mutu layanan diagnostik yang tepat dalam tindakan layanan kesehatan.

Abstract

Background: Hepatocellular Carcinoma (HCC) is the third leading cause of death in the world. One important aspect of lesion measurement in predicting HCC grading on Magnetic Resonance images is the ADC value obtained by performing Region of Interest can be a variation in shape size of Freehand, Circle, or Point voxel.Methods: Analytical quantitative research by comparing three shapes sizes ROI on the value of ADC in cases of HCC. Data was collected at the Radiology Installation of hospitals in Jakarta from 50 patients who underwent liver MRI with DWI-ADC Map images between January and October 2023. Analysis of data using Friedman test statistical test followed by Dunnet post hoc test.Results: ADC value for Freehand ROI was 1.33x10-3 mm2/s, Circle ROI was 1.31x10-3 mm2/s and Point Voxel ROI was 1.23x10-3 mm2/s. The statistic p0.05 means that there is a significant difference in ADC values between Point Voxel and Freehand and Circle ROI.Conclusions: ROI with different size shapes (Freehand, Circle, Point Voxel) affects ADC value. Circle ROI is recommended to evaluate HCC because the placement of the ROI can avoid inhomogeneous areas when measuring the ADC value on an MRI of the Liver with Hepatocellular Carcinoma.

Abstract

MR Spectroscopy (MRS) can help determine the ratio of brain metabolite spectrum results, in diagnosing brain disorders, especially brain tumors. In MRS, the use of different Time Echo (TE) parameters will affect the results of the metabolite spectrum obtained, as well as the signal intensity at different peak and ratio values. MRS can be performed using short and long TE. This study aims to analyze the differences in peak values in the spectrum of choline, creatine and NAA metabolites and to analyze the comparison of MRS metabolite spectrum results using different TE value variations. The type of research is quantitative analytic with data collection methods using observation, experiments, measurements and literature studies. From the results of the research that has been done, it can be concluded that the use of different short and long TEs affects the results of the spectrum graph, affecting different peak values and ratio values. Both cannot be mutually exclusive, because they have their respective roles in establishing a diagnosis, so the use of this TE variation must be combined in order to establish a diagnosis.

Abstract

The set-up aims to find out the value of the shift that occurs while the patient is undergoing the irradiation process on the X-axis (right-left), Y-axis (caudal-cranial), and Z-axis (anterior-posterior). The procedure for collecting research data is by making direct observations and being involved in measuring set-up shifts. The data used amounted to 20 nasopharyngeal cancer patients. Set-up shift measurement data were taken sequentially from fractions 1-33 for each patient using 4 and 9 points locks masks. Analysis of statistical test data using SPSS version 25, to determine the effect of using 4 and 9 points locks masks on shifts in nasopharyngeal cancer irradiation set-up patients with fraction group: Group 1 (fraction 1), Group 2 (Fraction 2 – 15), Group 3 (16-33)  using the Wilcoxon test because the normality test results were not fulfilled. If the p-value ≤ 0.05, there is an effect of using 4 and 9 points locks mask on shifts, while for p-value ≥ 0.05, there is no effect of using 4 and 9 points locks mask on set-up shifts in nasopharyngeal cancer irradiation set-up. The results of the shift in the set-up of 4 and 9 points lock irradiation vertically in the lateral, longitudinal, and vertical directions tend to be positive (left, caudal, posterior). There was no effect of all fraction groups using 4 and 9 points locks on the shift in nasopharyngeal cancer irradiation set-up p-value> 0.05.

Abstract

Background: Signal to noise ratio (SNR) is defined as the ratio of the amplitude of the signal received by the coil to the amplitude of the noise. Methods: This research was quantitative alongside an observational approach conducted at the Radiology Installation of Satya Negara Hospital, North Jakarta. Alongside a research population of Lumbar MRI patients with HNP clinical indication from October to November 2022. The research sample was ten patients aged around 25-50 years with a diagnosis of HNP. Furthermore, an MRI examination was carried out using T2 STIR and T2 Fat Saturation sequences. Hence, the results of the Lumbar MRI image were ROI performed on common areas alongside the Corpus, Discus, CSF, Spinal Cord, and HNP area. Results: This research showed there was a significant difference in SNR values in the T2 STIR and T2 Fat Saturation sequences in common areas with a p-value of > 0.05. There was no significant difference in SNR values in the HNP-experienced area with a p-value of < 0.05. Conclusions: After a statistical test using the Paired Sample T Test, the test results obtained were p value > 0.05, namely 0.692 for the SNR value on the results of the MRI Lumbar sagittal section of the sequence T2 STIR and T2 Fat saturation in the Lumbar area experiencing HNP, which means that Ho was accepted, which means that there was no significant difference in SNR values between the T2 STIR and T2 Fat saturation sequences in the lumbar tissue that experienced HNP. 2. The SNR value of MRI images of the lumbar sagittal section of the sequence T2 STIR and T2 Fat saturation in normal lumbar tissue including Corpus, Discus, CSF, the test results obtained are p-value <0.05. This means that Ho was rejected, which means there was a significant difference in SNR values between the T2 STIR and T2 Fat saturation sequences. In the spinal cord area, the test results obtained were p value > 0.05. This meant that Ho was accepted, which meant there was no significant difference in SNR values between the T2 STIR and T2 Fat saturation sequences.
