Essence of postmortem computed tomography for in-hospital deaths: what clinical radiologists should know
AbstractPostmortem computed tomography (CT) is an essential tool for investigating the causes of death. Postmortem CT has characteristic imaging findings and should not be interpreted in the same manner as clinical antemortem images. In analyzing the cause of death in in-hospital death cases using postmortem images, it is crucial to understand early postmortem and post-resuscitation changes. In addition, it is essential to understand the limitations of diagnosing the cause of death or significant pathology relating to death on non-contrast-enhanced postmortem CT. In Japan, there has also been social demand to establish a s...

Compressed sensing cine imaging with higher temporal resolution for analysis of left atrial strain and strain rate by cardiac magnetic resonance feature tracking
ConclusionHigher temporal resolution led to significantly higher measured LASR values in CMR-FT. Furthermore, the addition of CS reduced scan time and did not affect LA longitudinal strain or SR analysis. (Source: Japanese Journal of Radiology)

Value of fat-suppressed T2-weighted imaging for predicting short-term pain relief after sclerotherapy for venous malformations in the extremities
ConclusionA lesion size of 50  mm or less, a well-defined margin, a cavitary type, and no drainage vein on FS-T2WI were significant features for predicting short-term pain relief after polidocanol sclerotherapy for painful VMs in the extremities. (Source: Japanese Journal of Radiology)

Relationship of computed tomography quantified visceral adiposity with the severity and complications of acute pancreatitis: a systematic review
AbstractWhilst obesity and visceral adipose tissue (VAT) have been reported to be associated with an increased risk of severe AP, the established predictive scoring systems have not yet encompassed the impact of obesity or visceral adiposity. In the acute setting, computed tomography (CT) is often performed to assess AP severity and associated complications. With the added benefit of quantifying body fat distribution, it can be opportunistically used to quantify visceral adiposity and assess its relationship with the course of AP. This systematic review identified fifteen studies evaluating the relationship between viscera...

Multisite harmonization of diffusion tensor image analysis along the perivascular space using the COMBined Association Test
ConclusionThis study demonstrates the application of COMBAT harmonization to eliminate between-scanner, site, and protocol variations in the ALPS index calculated from DTI-ALPS using dMRI and possibly facilitate the use of the ALPS index in multi-center studies.

Radiomics in gastrointestinal stromal tumours: an up-to-date review
AbstractGastrointestinal stromal tumours are rare mesenchymal neoplasms originating from the Cajal cells and represent the most common sarcomas in the gastroenteric tract. Symptoms may be absent or non-specific, ranging from fatigue and weight loss to acute abdomen. Nowadays endoscopy, echoendoscopy, contrast-enhanced computed tomography, magnetic resonance imaging and positron emission tomography are the main methods for diagnosis. Because of their rarity, these neoplasms may not be included immediately in the differential diagnosis of a solitary abdominal mass. Radiomics is an emerging technique that can extract medical ...

Non-contrast dual-energy CT using X-map for acute ischemic stroke: region-specific comparison with simulated 120-kVp CT and diffusion-weighted MR images
ConclusionsX-map is useful to detect EIC, especially in deep white matter, and may also provide additional information in acute ischemic lesions where DWI cannot be detected. (Source: Japanese Journal of Radiology)

A look at radiation detectors and their applications in medical imaging
AbstractThe effectiveness and precision of disease diagnosis and treatment have increased, thanks to developments in clinical imaging over the past few decades. Science is developing and progressing steadily in imaging modalities, and effective outcomes are starting to show up as a result of the shorter scanning periods needed as well as the higher-resolution images generated. The choice of one clinical device over another is influenced by technical disparities among the equipment, such as detection medium, shorter scan time, patient comfort, cost-effectiveness, accessibility, greater sensitivity and specificity, and spati...
