PURPOSE To compare conventional T2-weighted spin-echo imaging with a rapid acquisition relaxation enhanced (RARE) technique in the routine evaluation of lumbar degenerative disk disease. METHODS Thirty consecutive patients referred for evaluation of the lumbar spine for suspected degenerative disk disease were evaluated with sagittal and axial T1-weighted spin-echo, conventional T2-weighted s...

background: to assess the efficacy of luteal phase support (lps) with vaginal progesterone (p) on pregnancy rates of the stimulated intrauterine insemination (iui) cycles in couples with unexplained infertility (uei). materials and methods: this was a single-center, prospective, randomized, blinded control trial undertaken at a tertiary care university fertility center between october 2007 and ...

BACKGROUND Current guidelines for the use of implantable cardioverter-defibrillators (ICDs) are broad and significantly increase the cost of caring for patients with heart failure. In an effort to identify the specific subset of patients who benefit from this therapy, the predictive value of numerous echocardiographic parameters have been studied. Severe diastolic dysfunction has been shown to ...

We evaluated 56 consecutive patients with newly diagnosed lymphoma including 48 with non-Hodgkin's lymphoma (NHL) and 8 with Hodgkin's disease to determine the clinical and prognostic significance of magnetic resonance imaging (MRI) of the femoral marrow. MR images of the femoral marrow were obtained by the T1-weighted spin echo method and the short TI inversion recovery technique. Abnormal "po...

This paper deals with metallographic studies and ultrasonic investigations of acoustic birefringence in the base metal heat affected zone welded specimens ASTM 1020 steel under uniaxial tension low-cycle fatigue. We examined microstructural changes on surface using optical microscope. It was found that development slip bands differs zone. The pulse echo method used for determination velocities ...
