Abstract

Background: Multiphase abdominal CT is a radiological imaging procedure using contrast media to detect abnormalities or diseases of internal abdominal organs. The development of Dual Energy CT (DECT) technology, particularly the liver VNC feature, enables the reconstruction of virtual non-contrast (VNC) images from post-contrast data, potentially eliminating the need for a true non-contrast (TNC) phase. This study aims to analyze anatomical information differences between TNC and VNC images and determine the most optimal image type for detecting abdominal masses.Methods: This research employed a quantitative experimental approach involving 10 patients who underwent multiphase abdominal CT at RSPAU Dr. Suhardi Hardjolukito. Comparative anatomical data between TNC and VNC images were evaluated by two radiology specialists. Inter-rater agreement was assessed using Cohen’s Kappa test, while the Wilcoxon test was used to analyze image information differences. To identify the most optimal anatomical image, the mean ranks of TNC and VNC were compared.Results: The results showed no significant anatomical information difference between VNC and TNC images in evaluating abdominal parenchyma, lesions, and vascularization, with a p-value of 0.083. In terms of mean rank, VNC had a value of 1.00, while TNC had 0.00, categorized as negative ranks, indicating that VNC was rated lower than TNC. Thus, the TNC algorithm is considered superior to VNC, even though most data showed no difference between the two image types.Conclusion: VNC images may serve as an alternative to TNC in multiphase abdominal CT, especially for abdominal mass cases. Future research is recommended to incorporate Hounsfield Unit (HU) and noise analysis and to consider integrating the VNC feature into dual-energy CT protocols.

Abstract

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.

Abstract

Background: The thyroid gland is highly sensitive to radiation and can easily be exposed during panoramic dental imaging. Although BAPETEN sets the annual public dose limit at 1 mSv, and ICRP 103 suggests a specific limit of 0.04 mGy per year for the thyroid, the use of personal protective equipment (PPE) is still often neglected in daily practice. This study aimed to assess how much radiation the thyroid receives during panoramic dental examinations without PPE.Methods: This study used a descriptive quantitative approach and was conducted at the Radiology Department of the Regional Dental and Oral Hospital, South Sulawesi. Ten patients undergoing panoramic radiography were selected. The thyroid radiation dose was calculated using five formulas: exposure dose, scatter dose, absorbed dose, equivalent dose, and effective dose. Technical factors such as tube voltage, current, exposure time, and distance to the thyroid were also recorded.Results: The absorbed dose to the thyroid gland obtained from 10 patients ranged from 0.0139 mGy to 0.0239 mGy, with a mean value of 0.0165 mGy and a standard deviation of 0.0035 mGy. These results indicate a relatively narrow distribution despite variations in patient body size and exposure parameters. All measured doses remained well below the annual organ dose limit of 0.04 mGy, as recommended by the International Commission on Radiological Protection (ICRP). However, existing literature has highlighted that even low-dose radiation exposures, when repeated and unshielded, may increase the stochastic risk of developing thyroid cancer—particularly in younger or genetically predisposed individuals. While the current findings confirm that radiation exposure during panoramic dental examinations is within acceptable limits, they also underscore the need for precautionary measures. The results support the practical implementation of the ALARA (As Low As Reasonably Achievable) principle, especially through the consistent use of thyroid shields during panoramic imaging, as a critical component of evidence-based radiation protection strategies.Conclusions: Panoramic dental imaging without thyroid shielding still produces radiation doses that are within acceptable limits. However, it is strongly recommended that PPE be used consistently, along with adherence to the ALARA principle, to ensure maximum patient safety.

Abstract

Background: Nucleus Pulposus Hernia (HNP) in the cervical region is a degenerative condition that can cause pressure on the spinal nerve. Magnetic Resonance Imaging (MRI) is the primary imaging modality for the diagnosis of HNP, but it has a long acquisition time limitation, which risks causing artifacts due to patient movement. The use of GRAPPA parallel imaging techniques can speed up acquisition, but lower the signal-to-noise ratio (SNR). This study aims to evaluate the effect of wavelet denoising filters on improving the quality of images and cervical MRI information of T2 TSE GRAPPA sequences in HNP patients.Methods: The study used a pre-experimental was conducted on 16 cervical HNP patients at Budi Rahayu Hospital Pekalongan. Acquisitions are carried out with acceleration factors 2, 3, and 4. Subjective analysis of image quality by three radiologists was performed on five anatomical structures (disc, corpus, spinal cord, CSF, and spinesus process). Data were assessed using the Cohen's Kappa test for fit between assessors and the Friedman test to compare SNR and CNR values between acceleration factors.Result: The application of wavelet denoising filters significantly increased SNR and CNR values (p = 0.0174 and p = 0.0175). R-factor 3 produced the best overall image quality with the highest Kappa value of 0.681 in the R1*R2 grader pair, indicating substantial conformity. The highest mean rank for visual quality was found in the spinal cord (R-factor 2 = 1.17), while the CSF, corpus, and disc showed the best quality in R-factor 3. This technique has been proven to retain critical diagnostic information with more efficient acquisition times.Conclusions: The combination of GRAPPA with wavelet denoising filters on T2 T2 sequence cervical MRI GRAPPA significantly improved image quality, especially at R-factor 3. These results show that this method is effective in reducing noise and preserving anatomical details, thereby improving the accuracy of cervical HNP diagnosis and patient comfort during the examination.

Abstract

Background: Magnetic Resonance Imaging (MRI) is a non-invasive imaging modality essential for evaluating complex anatomical structures such as the knee joint. MRI allows multiplanar imaging with high soft tissue contrast resolution. In knee imaging, the sagittal plane is particularly effective in assessing pathologies and visualizing structures like cartilage, menisci, bones, and ligaments (ACL and PCL). Proton Density Weighted (PDW) sequences combined with Spectral Adiabatic Inversion Recovery (SPAIR) fat suppression are commonly used to enhance soft tissue visualization. The image quality in SPAIR sequences is significantly influenced by the Time Inversion (TI) parameter. This study aimed to analyze the impact of varying TI values on the image quality of sagittal PDW SPAIR MRI of the knee joint, focusing on anatomical detail and contrast resolution.Methods: This research used a quantitative analytical method with an experimental approach. The study was conducted at the Radiology Department of Pertamina Central Hospital from March to April 2025. Ten knee MRI examinations were selected as samples. Image quality was assessed by three radiologists using a structured scoring questionnaire. The data were analyzed using non-parametric statistical tests, including Friedman and Wilcoxon Signed-Rank tests.Results: The Friedman test revealed statistically significant differences in anatomical detail (χ²(2) = 15.000, p = 0.001) and contrast resolution (χ²(2) = 17.882, p = 0.000) across the three TI values (100 ms, 160 ms, and 200 ms). Post-hoc Wilcoxon analysis showed that both TI 160 ms and 200 ms provided significantly higher image quality than 100 ms (p 0.017) in both parameters. However, no significant differences were found between TI 160 ms and 200 ms (p = 0.506 for anatomical detail, p = 0.273 for contrast resolution). Among the values tested, TI 160 ms demonstrated consistent and optimal scores for both image clarity and contrast.Conclusions: A TI value of 160 ms in the PDW SPAIR sequence is recommended as the optimal parameter for producing superior sagittal MRI images of the knee joint, particularly in terms of anatomical clarity and contrast resolution.

Abstract

Background: Ischemic stroke is a critical condition detectable through head CT scans, where windowing techniques significantly enhance brain tissue visualization. At Bethesda Hospital Yogyakarta, differing windowing protocols are used in the Emergency and Main Radiology Departments, yet no standardized stroke-specific window has been established. This study aims to identify the differences in anatomical information in head CT scans with various windowing settings and to determine the most optimal windowing protocol.Methods: This research is a quantitative-experimental study conducted at Bethesda Hospital Yogyakarta involving 10 patients with ischemic stroke, using variations of windowing settings: WW 120 HU WL 60 HU, WW 100 HU WL 35 HU, and WW 40 HU WL 40 HU. The image results were evaluated by two respondents based on the anatomical information of brain parenchyma, insular cortex, internal capsule, left and right cerebral hemispheres, and brain sulci. The data analysis was performed using the Friedman statistical test.Results: The results of the study showed that the WW 100 HU WL 35 HU setting provided the most informative anatomical visualization across all evaluated brain structures. In contrast, WW 120 HU WL 60 HU was the least informative for the brain parenchyma and insular cortex, while WW 40 HU WL 40 HU offered moderate clarity for most structures but was suboptimal for the brain parenchyma. These differences were confirmed by the Friedman test, with a p-value 0.05.Conclusions: There were differences in anatomical information across the various windowing settings in head CT scan examinations for ischemic stroke cases. In addition, the highest overall and individual anatomical mean rank was found in the WW 100 HU WL 35 HU windowing setting, with a value of 2.95.
