Reproducibility of automated calculation technique for diffusion tensor image analysis along the perivascular space
ConclusionThe vALPS index based on DTI-ALPS maintaining tensor vector orientation information has higher reproducibility than the ALPS index. This result encourages a multisite study on the ALPS index with a large sample size and helps detect a subtle pathological change in the ALPS index. (Source: Japanese Journal of Radiology)

Characterizing the penumbras of white matter hyperintensities in patients with cerebral small vessel disease
ConclusionsOur findings revealed that DTI/DKI and ASL can show structural and blood flow changes in brain tissue surrounding WMHs. In DWMHs, the blood flow penumbra was larger than the structural penumbra, while in PVWMHs, the blood flow penumbra was almost the same as the structural penumbra.

A retrospective study of locally advanced cervical cancer cases treated with CT-based 3D-IGBT compared with 2D-IGBT
ConclusionThe 2/3-year LC of the 3D-IGBT group was excellent and PFS also tended to improve. Care should be taken with concomitant use of bevacizumab after radiotherapy. (Source: Japanese Journal of Radiology)

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.

The need of radiotherapy optimization for glioblastomas considering immune responses
AbstractGlioblastoma is the most common of malignant primary brain tumors and one of the tumors with the poorest prognosis for which the overall survival rate has not significantly improved despite recent advances in treatment techniques and therapeutic drugs. Since the emergence of immune checkpoint inhibitors, the immune response to tumors has attracted increasing attention. Treatments affecting the immune system have been attempted for various tumors, including glioblastomas, but little has been shown to be effective. It has been found that the reason for this is that glioblastomas have a high ability to evade attacks f...

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...

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)

Contrast-induced anaphylaxis: does it occur in the medical environment and is it being responded to appropriately?
ConclusionAnaphylaxis occurred within 30 min after contrast injection in the majority of the cases, but times were widely distributed. Only in 75.5% of cases, appropriate primary treatment was performed, and the importance of keeping exact time records in patients’ charts should be re-emphasized.
