Hypertension is associated with substantial morbidity in Japan. The aim of this work was to evaluate whether hypertension is associated with white matter microstructural changes by using diffusional kurtosis imaging (DKI). ⋯ Our study suggests that microstructural white matter changes occur in middle-aged men with hypertension, even before the onset of cerebrovascular disease. Thus, DKI might be used as a screening tool for risk of cerebrovascular disease. This highlights the need to further elucidate the relationship between hypertension and DKI of the brain.

Duplication of the trachea is an extremely rare condition that has been infrequently reported in the medical literature. We report an adult case with complete tracheal duplication associated with unilateral atelectasis, which was incidentally detected by computed tomography. Tracheal duplication should be considered as a possible cause of severe atelectasis in adults.

Hemorrhage is a finding of clinical fat embolism syndrome. The purpose of the present study was to evaluate the occurrence of hemorrhage in the cat brain by SW MR imaging after infusion of triolein as a bolus or as an emulsion into the carotid artery. ⋯ SW images revealed hemorrhage in lesion hemispheres infused with triolein bolus. However, there was no evidence of hemorrhage infused with emulsified triolein. Thus, the occurrence of hemorrhage in cerebral fat embolism may depend on fat status.

Pulmonary alveolar microlithiasis: imaging characteristics of planar and SPECT/CT bone scan versus 18F-FDG and 18F-sodium fluoride PET/CT scanning.
Pulmonary alveolar microlithiasis (PAM) is a very rare disease in which multiple microscopic calcium phosphate microliths are deposited within the alveoli of both lungs. A lung biopsy is considered to be definitive for final diagnosis; however, non-invasive imaging modalities such as chest X-ray, HRCT scan and (99m)Tc-MDP bone scan suggest the diagnosis in the vast majority of patients. ⋯ Interestingly, we noted that (18)F-sodium fluoride PET/CT is a superior modality in characterization and assessment of the extent of disease in PAM compared to all other non-invasive imaging modalities. Thus, we recommend that (18)F-sodium fluoride PET/CT should be the investigation of choice in PAM.

To investigate the diagnostic capability of multidetector computed tomography for detecting non-occlusive mesenteric ischemia (NOMI). ⋯ D SMA and D SMV were significantly smaller in NOMI patients than in the controls and D SMV is a more significant parameter than D SMA.
