PURPOSE The frequency of lung cancer in patients with idiopathic pulmonary fibrosis (IPF) is higher than that of general population. To evaluate CT findings of lung cancer associated with IPF, we analyzed 32 patients with lung cancer associated with IPF. METHOD We analyzed retrospectively 32 patients with histologically confirmed lung cancer out of 244(More)
OBJECTIVE To evaluate the radiographic and MR appearance of idiopathic synovial osteochondromatosis of the hip. MATERIALS AND METHODS Radiographs and MR images of 15 patients with idiopathic synovial osteochondromatosis of the hip were assessed. The former were analysed in terms of the presence of 1) juxta-articular calcified and/ or ossified bodies, 2)(More)
PURPOSE Our goal was to correlate high-resolution MR images of the tibiofibular syndesmosis with anatomic sections. METHOD MRI was performed inside a local gradient coil on six cadaveric feet taped in 10-20 degrees dorsiflexion and 40-50 degrees plantar flexion by using axial and coronal T1-weighted SE sequences. After imaging, the specimens were frozen(More)
OBJECTIVE The aim of this study is to evaluate the reliability of MR imaging to predict the stability of the torn anterior cruciate ligament (ACL) after complete recovery of the ligament's continuity. MATERIALS AND METHODS Twenty patients with 20 knee injuries (13 males and 7 females; age range, 20-54) were enrolled in the study. The inclusion criteria(More)
RATIONALE AND OBJECTIVES The authors evaluate the functional changes in patients with cervical radiculopathy and increasing symptoms after provocative maneuvers at flexion, extension, axial rotation, and coupled motions of the cervical spine. METHODS Twenty-one patients with cervical disc herniation (n = 17) or cervical spondylosis (n = 4) in whom(More)
STUDY DESIGN In vivo flexion-extension and axial rotation magnetic resonance imaging (MRI) studies of the cervical spine were performed inside a positioning device. OBJECTIVE To determine the functional changes of neuroforaminal size that occur during flexion-extension and axial rotation of the cervical spine in healthy persons. SUMMARY OF BACKGROUND(More)
Serial changes of bone density in 26 femora and 22 tibiae that underwent leg lengthening by distraction osteogenesis were investigated by measuring the pixel value shown on a picture archiving and communication systems (PACS) monitor. The pixel value of the original cortex did not change significantly until the external fixator was removed. The pixel value(More)
RATIONALE AND OBJECTIVES To evaluate the effect of the transverse ligament on translation of the menisci. METHODS Six cadaveric knees were examined by MR imaging inside a positioning device before and after transecting the transverse ligament. The knees were examined at various positions: extension, 30 degrees of flexion, 60 degrees of flexion, and full(More)
OBJECTIVE To estimate and compare radiation exposure and intervention time during lumbar epidural steroid injection (ESI) 1) under different practitioners and methods with continuous fluoroscopic monitoring, and 2) under one practitioner with different methods and monitoring. MATERIALS AND METHODS We consecutively recruited 804 patients who underwent(More)
PURPOSE The detection and localization of cerebrospinal fluid (CSF) leakage in patients with spontaneous intracranial hypotension (SIH) is important. The aim of this study was to evaluate the usefulness of multidetector CT (MDCT)-myelography in patients with SIH. METHODS A radiologist retrospectively searched the electronic database to find the patients(More)
