Model-based iterative reconstruction for multi-detector row CT assessment of the Adamkiewicz artery.

Purpose: To determine if model-based iterative reconstruction (MBIR) can improve visualization of the Adamkiewicz artery on multi-detector row computed tomographic (CT) images compared with adaptive statistical iterative reconstruction (ASIR) and filtered back projection (FBP).

Materials And Methods: This retrospective study was approved by the institutional review board, and written informed consent for the CT examination was obtained. Thirty-three patients underwent contrast material-enhanced 64-section multi-detector row CT for assessment of aortic aneurysm or dissection.

[Long-term follow-up of a case of unilateral retinitis pigmentosa].

Background: Unilateral retinitis pigmentosa is a retinal dystrophy affecting only one eye, the fellow eye being affected neither functionally nor in fundus appearance. There are relatively few cases of unilateral retinitis pigmentosa being followed for more than 5 years.

Case: An 18-year-old woman complaining of blurred vision of left eye was found to have left visual field concentric contraction.

[Case of Heerfordt's syndrome presenting polyneuropathy].

Background: Acute presentation of sarcoidosis with the combination of uveitis, parotid gland enlargement, facial nerve palsy, and fever is called Heerfordt's syndrome. Clinically recognizable involvement of the nervous system occurs in < 10% of patients with sarcoidosis, and polyneuropathy in 24% with neurosarcoidosis.

Case: A 28-year-old woman diagnosed with Guillain-Barré syndrome was admitted and treated for a month in the Department of Neurology, Mie University hospital.

Focal spared area in fatty liver mimicking a tumor.

A focal fatty liver change may be associated with several conditions related to diffuse hepatic steatosis, such as a diffuse fatty liver change. Using ultrasonography, the focal fatty liver change appears more frequently as hyperechoic and less frequently as hypoechoic areas in the liver. We report a rare case of a focal fatty liver change in which an area was spared in fatty liver.
