Conventional magnetic resonance imaging (MRI) at term equivalent age (TEA) is suggested to be a reliable tool to predict the outcome of very premature infants. The objective of this study was to determine simple reproducible MRI indices, in premature infants and to analyze their neonatal determinants at TEA. A cohort of infants born before 32 weeks gestational age (GA) underwent a MRI at TEA in...

The aim of this study was to correlate carotid black blood MRI based measurements with those obtained by ultrasound intima-media thickness (IMT). Seventeen patients with intermediate to high Framingham cardiovascular risk score underwent both carotid ultrasound and rapid extended coverage double inversion recovery black blood carotid MRI. Overall, there was good correlation between wall area, w...

OBJECTIVES The study compared flow reserve indices by magnetic resonance imaging (MRI) with quantitative measures of coronary angiography and positron emission tomography (PET). BACKGROUND The noninvasive evaluation of myocardial flow by MRI has recently been introduced. However, a comparison to quantitative flow measurement as assessed by PET has not been reported in patients with coronary a...

Objectives: To establish a slowly progressive, reproducible rat model of disc degeneration and investigate the relationship between MRI and histology in the long-term progression of disc degeneration. Materials and methods: The intervertebral discs of caudal spine in rats were punctured laterally, using 20-gauge sterile needles, 5 mm depth from the skin to the middle of the appropriate disc. Th...

Purpose The purpose of this study was to investigate the impact of varying knee flexion and quadriceps activity on patellofemoral indices measured on magnetic resonance imaging (MRI). Materials and Methods MRI of the knee was performed in 20 patients for indications other than patellar or patellofemoral pathology. Axial and sagittal sequences were performed in full extension of the knee with ...

ECG criteria for left ventricular hypertrophy (LVH) were mostly validated using left ventricular mass (LVM) as measured by M-mode echocardiography. LVM as measured by cardiac MRI has been demonstrated to be much more accurate and reproducible. We reevaluated the sensitivity and specificity of 4 ECG criteria of LVH against LVM as measured by cardiac MRI. Patients with systemic hypertension (n=28...

Cardiomyopathy is an important and frequently life limiting manifestation of Friedreich's ataxia (FA), the most prevalent form of autosomal recessive ataxia. Left ventricular mass is used as primary outcome measure in recent intervention studies but systematic analyses of FA cardiomyopathy are sparse. To assess cardiac hypertrophy by cardiac magnetic resonance imaging (MRI) in vivo, we assessed...

OBJECTIVE All patients with stage IB1 cervical cancer do not need to undergo parametrectomy. Some low-risk criteria for parametrial involvement (PI) have been proposed based on pathological findings. The aim of this study was to determine pretreatment risk factors for PI in stage IB1 cervical cancer. METHODS We retrospectively reviewed 115 patients with stage IB1 cervical cancer who underwent...
