Fig. 1.-A, Noncontrast CT scan shows vague area of increased attenuation adjacent to head of right caudate nucleus (arrow). B, Coronal T1-weighted (700/ 20/ 4) MR image shows area of decreased signal in white matter adjacent to, and extending into, head of right caudate nucleus (arrow). C, Axial T1-weighted (600/ 20) postcontrast MR image shows no significant contrast enhancement (arrow). D, Ax...

High-resolution magnetic resonance (MR) imaging plays a pivotal role in the pretreatment assessment of primary rectal cancer. The success of this technique depends on obtaining good-quality high-resolution T2-weighted images of the primary tumor; the mesorectal fascia, peritoneal reflection, and other pelvic viscera; and superior rectal and pelvic sidewall lymph nodes. Although orthogonal axial...

The aim of this study was to compare magnetic resonance enterography (MRE) findings with those of video capsule endoscopy (VCE) or conventional gastrointestinal radiography (CGR) in pediatric patients with small bowel Crohn's disease. A total of 55 cases of small bowel Crohn's disease that were diagnosed through clinical, laboratory, surgical and histopathological findings were reviewed. Prior ...

Anthony A. Romeo, MD, Department of Orthopaedic Surgery, Rush University Medical Center, Chicago, Illinois. B C A A 72-year-old woman presents with chronic shoulder pain subsequent to a fall that has not responded to conservative treatment. She tells you that she “wants it fixed.” T2-weighted coronal (A) and sagittal (B) and T1-weighted sagittal (C) magnetic resonance images are provided. What ...

An internal receiver coil was used to obtain high resolution transverse and oblique coronal magnetic resonance images of the anal sphincter in five normal volunteers and five patients. The internal sphincter had a high signal intensity on T1 weighted, T2 weighted, and STIR sequences whereas the conjoined longitudinal muscle and external sphincter had a low signal intensity. The internal sphinct...

PURPOSE To demonstrate normal MR anatomy of the substantia innominata and its changes in Alzheimer disease on MR imaging. METHODS Using a 1.5-T superconductive MR unit, thickness of the substantia innominata was measured on coronal thin-section images obtained in 22 patients with Alzheimer disease and 14 age-matched control subjects. Comparison of these images with postmortem specimens of hum...

A detailed evaluation of the MR appearance of the pituitary gland-cavernous sinus junction has not been described. In a series of coronal T1-weighted spin echo images without and with IV gadolinium, we noted the variable size and signal intensity of cavernous venous spaces adjacent to the pituitary gland and the inconsistent visualization of the dural membrane just lateral to the gland. Correla...

The term 'craniofrontonasal dysplasia' (CFND) was introduced by Cohen' in 1979 when describing a 14 year old girl with coronal craniosynostosis, hypertelorism, limitation of shoulder movement, and digital abnormalities. The child's mother was also affected. In the same volume of Birth Defects, Slover and Sujansky2 reported similar findings in three female sibs, both of whose parents had hyperte...

BACKGROUND The most-widely used visual rating scale (VRS) for medial temporal atrophy is the T1-weighted (T1W) coronal VRS developed by Scheltens et al. However, it is often difficult to use the T1W-coronal VRS in cases with limitations in obtaining T1W-coronal images. To overcome this issue, we modified the T1W-coronal VRS onto the axial plane. OBJECTIVE The purposes of this study were to va...
