Esophageal involvement in epidermolysis bullosa dystrophica: Clinical and roentgenographic manifestations
(Springer-Verlag, 1983-12)
Epidermolysis bullosa is a rare hereditary mechanobullous skin disorder. Four patients with esophageal involvement are reported. These cases and review of reported cases of epidermolysis bullosa dystrophica-recessive (EBD-R) ...
CT and ultrasound in abscess detection at specific anatomic sites: A study of 198 patients
(Elsevier, 1987)
Records of 902 patients with possible abdominal abscess were reviewed and of these 198 had abscesses on at least one occasion imaged either with ultrasound (US) or computed tomography (CT). There were 235 episodes of either ...
Staphylococcal esophagitis causing giant ulcers
(Springer-Verlag; Springer-Verlag New York, Inc., 1993-06)
A 29-year-old woman with Hodgkin disease developed odynophagia while receiving chemotherapy. Large esophageal ulcers due to staphylococcal infection of the mucosa were visualized by endoscopy and radiography. This unusual ...
Signal-to-noise measures for magnetic resonance imagers
(Elsevier, 1993)
The signal-to-noise ratio (SNR) in magnetic resonance imaging represents one of the system operating variables that must be determined both for evaluating the performance of different imaging protocols on a particular ...
Quantitative assessment of surface roughness using backscattered ultrasound: The effects of finite surface curvature
(Elsevier, 1994)
We have previously described a technique to quantify surface fibrillatory changes in osteoarthritic articular cartilage. In that study, the angular distribution of the scattered acoustic field from an insonifying source ...
Granulocytic sarcoma (chloroma) causing spinal cord compression
(Springer-Verlag, 1993-08)
Granulocytic sarcoma (chloroma) is a rare solid tumor of myelogenous stem cells, usually appearing in patients with acute myelogenous leukemia and less commonly in patients with chronic myelogenous leukemia or myeloproliferative ...
Retroperitoneal extraosseous ewing's sarcoma with renal involvement: US and MRI findings
(Elsevier, 1993)
A case of retroperitoneal extraosseous Ewing's sarcoma (EES) with renal involvement, which simulated an exophytic renal mass, is reported. EES is a rare soft tissue tumor that can occur anywhere in the soft tissues, but ...
Motion artifacts in quantitative magnetic resonance imaging
(Elsevier, 1986)
Several investigators have emphasized the potential value of quantitative relaxation times in the assessment of diseases. In performing such measurements using the spin-echo technique, we have encountered several anomalous ...
