Postmortem computed tomography lung findings in fatal of hypothermia.

To identify lung findings specific to fatal hypothermia on postmortem computed tomography (CT) imaging. Whole body CT scans were performed followed by full autopsy to investigate causes of death. There were 13 fatal hypothermia cases (group A) and 118 with other causes of death (group B).

Dynamic MR imaging of kidneys perfused with EOB-Gd-DTPA.

Gandolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA) is a hepatobiliary contrast agent for MRI. It was reported that Gd-EOB-DTPA is useful to detect liver tumors and differentially diagnose benign and malignant pathologies in the liver. Since Gd-EOB-DTPA partially accumulates in the hepatocytes and bile via various transporters after intravenous injection, signal intensity in the liver increases on T1-weighted images.

MR angiography for detecting the artery of Adamkiewicz and its branching level from the aorta.

Purpose: We evaluated the efficacy of magnetic resonance angiography (MRA) for detecting the artery of Adamkiewicz (AKA) and the vertebral level of its feeding arteries branching from the aorta.

Materials And Methods: Eighty-two patients (67 men, 15 women; aged 34 to 86 years, mean age 68.6 years) with thoracic descending and thoracoabdominal aortic lesions (aneurysm in 55, dissection in 25, coarctation in 2) underwent MRA to detect AKA.

Effects of blood flow control on clinical outcomes after ethanolamine oleate sclerotherapy for vascular malformations.

Purpose: The purpose of this study was to assess the control of nidus blood flow and the association between such control and clinical outcomes after ethanolamine oleate (EO) sclerotherapy for vascular malformations.

Materials And Methods: Morphological grades on magnetic resonance (MR) images (grades 1-3), preprocedure nidus blood flow control, and clinical results in 22 cases of vascular malformation were reviewed.

Results: Cases were subdivided by MR morphological grade as follows: grade 1, 3 patients; grade 2A, 6 patients; grade 3, 13 patients.

Double-subtraction maximum intensity projection MR angiography for detecting the artery of Adamkiewicz and differentiating it from the drainage vein.

Purpose: To evaluate the efficacy of double-subtraction magnetic resonance angiography (MRA) (subtraction of the subtracted venous phase image from the subtracted arterial dominant phase image) for depicting the artery of Adamkiewicz and differentiating it from the drainage vein.

Materials And Methods: A total of 170 patients (123 men, 47 women; aged 17-84 years, mean = 67 years), with a thoracoabdominal vascular lesion underwent MRA for detection of the artery of Adamkiewicz. MRA was performed as a five-phase dynamic-enhanced three-dimensional (3D) fast spoiled gradient recalled acquisition in steady state (GRASS) sequence on a 1.

Peripheral vascular malformations: imaging, treatment approaches, and therapeutic issues.

Peripheral vascular malformations are now described according to some accepted guidelines, and the principle of proper treatment (nidus ablation) is becoming clear. An appropriate classification scheme for vascular anomalies and definite indications for treatment are important to successful treatment overall. The findings from noninvasive imaging (ie, Doppler ultrasonography, computed tomography, or magnetic resonance imaging) in association with clinical findings are critical in establishing the diagnosis, evaluating the extent of the malformation, and planning appropriate treatment.

Usefulness of preoperative detection of artery of Adamkiewicz with dynamic contrast-enhanced MR angiography.

Purpose: To prospectively evaluate the detection of the artery of Adamkiewicz at magnetic resonance (MR) angiography and the effect such detection has on outcome after surgical graft placement in a series of patients with thoracoabdominal aortic disease.

Materials And Methods: This study had ethics committee approval, and written informed consent was obtained from all patients. Fifty patients (38 men, 12 women; age range, 47-83 years; mean age, 67.

Creation of individual ideally shaped stents using multi-slice CT: in vitro results from the semi-automatic virtual stent (SAVS) designer.

To plan stent-grafting for thoracic aortic aneurysm with complicated morphology, we created a virtual stent-grafting program [Semi Automatic Virtual Stent (SAVS) designer] using three-dimensional CT data. The usefulness of the SAVS designer was evaluated by measurement of transformed anatomical and straight stents. Curved model images (source, multi-planer reconstruction and volume rendering) were created, and a hollow virtual stent was produced by the SAVS designer.
