Intravoxel incoherent motion parameters in the evaluation of chronic hepatitis B virus-induced hepatic injury: fibrosis and capillarity changes.

Objective: To evaluate the diagnostic efficacy of intravoxel incoherent motion (IVIM) parameters in hepatitis B virus (HBV)-induced hepatic fibrosis using different calculation methods and to investigate histopathologic origins.

Materials And Methods: Liver biopsies from 37 prospectively recruited chronic hepatitis B patients were obtained. Twelve b-value (0-1000 s/mm) diffusion-weighted imaging (DWI) was performed with a 1.

Intraoperative rotation control in closed intramedullary nailing in tibia diaphyseal fractures: a prospective, randomised study.

The intraoperative determination of rotation in closed intramedullar nailing of tibial fractures is difficult. In this study, a more reliable method was used and it was a more practical means of checking rotation intra-operatively for tibia diaphysis fractures. 42 patients who presented with a unilateral tibia diaphyseal fracture.

Is It an Overlooked Injury? Magnetic Resonance Imaging Examination of Occult Talus Lesions Concomitant to Tibial Shaft Fracture.

Long-term studies have shown that 10% to 20% of patients continue to experience ankle pain years after tibial fracture, which causes poor functional results and dissatisfaction. The aim of this study was to show that there could be a talus injury in patients with a tibial shaft fracture and to reveal occult talus lesions with magnetic resonance imaging (MRI) examination. Fifty-two patients with a tibial shaft fracture, with closed epiphyses, not extending to the joint and with no problems in the application of MRI examination were included.

Functional evaluation of secondary renal amyloidosis with diffusion-weighted MR imaging.

Objectives: This study evaluated whether diffusion-weighted magnetic resonance imaging (DW-MRI) can be used to diagnose secondary renal amyloidosis looking specifically at the diagnostic efficacy of two apparent diffusion coefficient (ADC) measurement methods as they were used with DW-MRI.

Methods: The study included 24 amyloid nephropathy (AN) patients, 20 chronic kidney disease (CKD) patients, and 20 healthy volunteers (HV). ADC values were measured using two different methods: 1) the method of the region of interest indicators (ROIs) and 2) the method of drawing whole renal parenchyma (WP).

Temporal bone MRI with 3D-FIESTA in the evaluation of facial and audiovestibular dysfunction.

Purpose: To evaluate the clinical usefulness of magnetic resonance imaging (MRI) of the temporal bone using three-dimensional fast imaging employing steady-state acquisition (3D-FIESTA) sequences in patients with facial and audiovestibular dysfunction.

Methods: We retrospectively reviewed the MR images of 1263 patients who presented with hearing loss (n=429), peripheral facial palsy (n=96), tinnitus (n=341) or vertigo (n=397). There were 605 men and 658 women, with a mean age of 46.
