PURPOSE To analyze the correlation between the volume of herniated orbital contents and the amount of enophthalmos in orbital floor and wall fractures. MATERIALS AND METHODS Patients with secondary enophthalmos due to unilateral orbital floor and wall fractures were recruited. Computed tomography-assisted measurements of both orbits as well as of the amount of enophthalmos were performed. The...

The purpose of this editorial is to advocate further experimental work such as that which Muhle et al describe in this issue of the American Journal of Neuroradiology (page 1763). For spine imaging, patients are placed in a supine position, often with supports or cushions to enhance their comfort. This position, which minimizes the patient’s discomfort, may diminish any visible effect of spinal...

Although post-operative acquired internal hernias at the cesarean (C) section incision site of the uterus were reported previously, there is no case in the literature in which intestinal herniation into uterine cavity at a different site than C-section uterine incision was reported. We report here for the first case in which bowel was herniated into uterine cavity from an un-incised location. A...

Scalene myofascial pain syndrome is a regional pain syndrome wherein pain originates over the neck area and radiates down to the arm. This condition may present as primary or secondary to underlying cervical pathology. Although scalene myofascial pain syndrome is a well known medical entity, it is often misdiagnosed as being some other neck pain associated with radiculopathy, such as cervical d...

Endoscopy was used to determine the prevalence of subclinical gastroduodenal ulceration in 30 Dachshunds undergoing decompressive surgery for acute intervertebral disc prolapse. The endoscopy was performed on the day of admission and on the 3rd or 4th day after surgery. Three regions of the stomach (cardia, corpus and pylorus) and the proximal duodenum were visually inspected and biopsy samples...

The occurrence of paraesthesiae during occlusion of the circulation to a limb (ischaemic paraesthesiae) and after its restoration (post-ischaemic paraesthesiae) is well recognized. The ischaemic paraesthesiae consist of a soft, diffuse, tingling sensation felt at the periphery of the limb and lasting only a few minutes. The post-ischaemic paraesthesiae, which have been well demarcated by Merrin...

The purpose of this study was to compare the resulting full width at half maximum of slice sensitivity profiles (SSP) generated by several commercially available point response phantoms, and determine an appropriate imaging technique and analysis method. Four CT phantoms containing point response objects designed to produce a delta impulse signal used in this study: a Fluke CT-SSP phantom, a Ga...

The present case report describes the topographical anatomy and radiological study of an asymmetrical inferior articular process of a lumbar vertebra, which was detected during routine osteology teaching of undergraduate medical students. The inferior articular process of the lumbar vertebra on the left side was rudimentary, while that on the right was normal in size. On the left side an additi...
