Unenhanced 3D turbo spin echo MR angiography of lower extremity arteries: comparison with 128-MDCT angiography.

Purpose: This study aimed to investigate the feasibility and diagnostic power of unenhanced 3D turbo spin echo MR angiography sequence (a technique based on subtraction of corresponding images acquired in diastole and systole, Syngo Native Space-Siemens healthcare) to identify peripheral artery disease (PAD).

Materials And Methods: Thirty patients (619 arterial segments in total) suspected with PAD and who were assessed with lower extremity MDCT angiography were examined starting from the level of aortic bifurcation for both lower extremities by 3D native space MR angiography. Two readers assessed the image quality of native space MR angiography and number of lesions, their degrees of stenosis and localizations.

Unenhanced respiratory-navigated NATIVE TrueFISP magnetic resonance angiography in the evaluation of renal arteries: Comparison with contrast-enhanced magnetic resonance angiography.

Purpose: To compare unenhanced three-dimensional (3D) NATIVE true fast imaging with steady-state precession (TrueFISP) magnetic resonance (MR) angiography with the more conventional MR angiography technique obtained after intravenous administration of a gadolinium chelate in the evaluation of renal arteries and their branches in patients with suspected renal artery stenosis.

Materials And Methods: A total of 39 patients (25 men, 14 women) with a mean age of 51.4±17.

Radiological Findings of Michel Aplasia.

Introduction: Congenital abnormalities of the inner ear is the most common cause of neurosensory hearing loss. Michel inner ear deformity is a rare developmental anomaly refers to the total aplasia of the inner ear. It is caused by developmental arrest of otic placode early during the third week of gestational age.

Carotid and cerebral CT angiography using low volume of iodinated contrast material and low tube voltage.

Purpose: To evaluate image quality of carotid computed tomography angiography (CTA) using a low voltage (80kV) and low amount of iodinated contrast material.

Materials-methods: A total of 101 patients referred for carotid CTA were randomly assigned to receive a specific protocol. In group A patients received intravenous administration of contrast material at a dose of 1mL/kg and CTA examinations were performed at 100kV.

Anatomic variations of popliteal artery: Evaluation with 128-section CT-angiography in 1261 lower limbs.

Purpose: The purpose of this study was to evaluate the variations in popliteal artery branching in a large population on computed tomography angiography (CTA) using a 128-section configuration.

Materials And Methods: A total of 652 patients (532 men, 120 women) with a mean age of 61.7±18.
