Magnetic resonance imaging of normal lumbar intervertebral discs.
OBJECTIVE To study changes in midpoint lumbar disc heights in an asymptomatic Jordanian sample relative to age, sex, lumbar level and midvertebral heights. METHODS A total of 153 asymptomatic patients (87 males, age range 20-65 years; mean 43+/-12.1 and 66 females, age range 22-68 years; mean 47+/-13.7) were selected during the study period. All underwent midsagittal magnetic resonance imagin...
متن کاملMeasuring Dimensions of Lumbar Intervertebral Discs in Normal Subjects
Introduction: Disc degeneration is a natural aging process characterized by changes in appearance and chemical structure of the disc. This degeneration leads to back pain. In regard to the limitation of current therapeutical methods for patients with degenerated discs, arthroplasty has been suggested as an alternative method. To manufacture artificial discs for Iranians, determining normal lumb...
متن کاملDiscoscopic Findings of High Signal Intensity Zones on Magnetic Resonance Imaging of Lumbar Intervertebral Discs
A 32-year-old man underwent radiofrequency thermal annuloplasty (TA) with percutaneous endoscopic discectomy (PED) under local anesthesia for chronic low back pain. His diagnosis was discogenic pain with a high signal intensity zone (HIZ) in the posterior corner of the L4-5 disc. Flexion pain was sporadic, and steroid injection was given twice for severe pain. After the third episode of strong ...
متن کاملCorrelations between radiographic, magnetic resonance and histological examinations on the degeneration of human lumbar intervertebral discs.
CONTEXT AND OBJECTIVE There is controversy regarding which imaging method is best for identifying early degenerative alterations in intervertebral discs. No correlations between such methods and histological finds are presented in the literature. The aim of this study was to correlate the thickness of intervertebral discs measured on simple radiographs with the degree of degeneration seen on ma...
متن کاملIncidental extraspinal findings on magnetic resonance imaging of intervertebral discs
INTRODUCTION We aimed to evaluate pathological extraspinal findings and congenital anomalies/anatomical variations that were incidentally detected on the magnetic resonance imaging (MRI) scans of intervertebral discs, to find the frequencies of these incidental findings, and to emphasise the clinical importance of them. MATERIAL AND METHODS A retrospective study including 1031 consecutive pat...
