Summary: The study systematically compared the performance of CT/MRI LI-RADS category 5 (LR-5) for diagnosing HCC between 2017 and 2018 versions, finding no significant difference in sensitivity and specificity between the two versions. The most common underlying liver disease (hepatitis B or hepatitis C) was a significant factor contributing to the heterogeneity of sensitivities among studies for both versions.

Summary: This study aimed to compare the performance of the 2018 European Association for the Study of the Liver (EASL) criteria and the Liver Imaging Reporting and Data System (LI-RADS) criteria for noninvasive diagnosis of hepatocellular carcinoma (HCC). The results showed that there were no significant differences in sensitivity and specificity between the EASL criteria and LI-RADS criteria. Subgroup analyses also showed no significant differences for different size observations.

Summary: The purpose of this study is to determine the threshold for iodine quantification to distinguish between non-enhancing benign renal lesions and potential enhancing masses on portal venous dual-layer spectral computed tomography (CT), in order to reduce the need for additional multiphase CT. By analyzing the data, thresholds for non-enhancing lesions and enhancing masses were determined, which can help doctors make diagnoses and reduce unnecessary examinations.

Summary: In a selected, high-prevalence population, VP-DECT is considered an accurate imaging tool for diagnosing PE compared to CTPA. The sensitivity of VP-DECT images in per-patient analysis was 90.0%, with 100% specificity; while in per-lobe analysis, sensitivity ranged from 100% for the right lower lobe to 50% for the left upper lobe.

Summary: Comparative studies were conducted to compare the performance of Liver Imaging Reporting and Data System category 5 (LR-5) for diagnosing HCC between CT and MRI. The results showed that MRI had significantly higher sensitivity than CT in diagnosing HCC using LR-5. However, there was no significant difference in specificity between the two modalities. Subgroup analysis revealed that extracellular contrast agent-enhanced MRI had higher sensitivity than gadoxetic acid-enhanced MRI in diagnosing HCC.

Summary: The study analyzed the accuracy of non-contrast MRI in characterizing adnexal masses among 291 patients. It was found that a non-contrast MRI score of >= 4 was associated with malignancy with high sensitivity and specificity. The results suggest that non-contrast MRI studies can serve as a reasonable diagnostic alternative when intravenous contrast medium cannot be administered.

Summary: This study evaluated 112 cases with CT images taken before forensic autopsy and found that block-like and cast-like hyperdense areas in the right heart cavities could predict the presence of intracardiac blood clots at forensic autopsy.

Summary: The study found a weak but significant correlation between hepatic tissue T1 times on CMR and Hounsfield units on non-contrast CT. Hepatic T1 times were linked to impaired systolic function and higher natriuretic peptide levels.

Summary: The study found that fluid along the deep fascia was the only CT criterion significantly associated with NSTI and appeared to be more useful than the LRINEC score in diagnosing the condition.

Summary: This study evaluated focal multiple myeloma bone lesions using dual-energy CT-based virtual noncalcium (VNCa) bone marrow imaging in relation to the overall hematological disease status and MRI findings. The results showed that VNCa attenuation measurement allows differentiation between active and inactive disease, with higher attenuation indicating a higher likelihood of active disease.

Summary: This population-based study aimed to collect, analyze, and summarize the long-term trends in medical imaging use in Taiwan. The results showed that CT and MRI use has sharply increased in the past two decades, especially in the older age group, but the growth rates have slowed in recent years. The increase in imaging use has been associated with improved clinical outcomes, including higher life expectancy and reduced mortality rates, although further assessment is needed to demonstrate a direct link with imaging.

Summary: This study evaluated the reliability and accuracy of thick maximum intensity projection (MIP) CTA images in detecting large-vessel occlusion (LVO) in the anterior circulation in patients with acute stroke. The results showed substantial interobserver agreement using 3mm MIPs and almost perfect agreement using 2mm MIPs. Sensitivity and specificity of 3mm and 2mm MIPs were not significantly different, indicating that thick axial MIPs are not useful for detecting proximal LVO in the anterior circulation.

Summary: Contrast-enhanced US (CEUS) plays an important role as a supplement to CT or MRI, especially in the liver and kidney. Its advantages lie in superior contrast resolution, real-time continuous scanning, pure intravascular nature, portability, and safety, making it particularly suitable for patients with renal impairment or CT/MRI contrast agent allergy.

Summary: Total kidney volume measurements by 3D ultrasound and ultrasound ellipsoid show similar level of underestimation compared to MRI ellipsoid, with variable misclassification of Mayo Clinic imaging classes. Predictions of high-risk Mayo Clinic imaging classes by all methods have high positive predictive value, but 3D ultrasound and ultrasound ellipsoid have lower negative predictive value and sensitivity compared to MRI ellipsoid. Ultimatey, ultrasound ellipsoid is a simpler and more easily accessed method for predicting high-risk imaging classes.
