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 ...
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 ...
Three dimensional CT of central lung tumors
(Elsevier, 1990)
Three-dimensional computed tomography (CT) reconstructions and conventional CT were compared with surgical /pathological findings in seven patients with central lung tumors, in order to assess accuracy in predicting the ...
Musculoskeletal power Doppler

MRI in osteoarthritis of the hip: Gradations of severity
(Elsevier, 1988)
In a prospective study, 10 patients with well-documented osteoarthritis (O.A.) of the hips were imaged using spinecho pulse sequences (TR = 0.5 to 1.5 s and TE = 28 to 60 ms). After analyzing the changes observed, an MR ...
Tumoral calcinosis: radiologic-pathologic correlation
(Springer-Verlag; International Skeletal Society, 1995-11)
Tumoral calcinosis is a frequently misdiagnosed disorder. This study details the radiologic and pathologic characteristics of tumoral calcinosis that distinguish it from most other entities.
Ultrasonographic diagnosis of extremity masses
(Springer-Verlag; International Skeletal Society, 1981-05)
Radiographic examination of soft tissue extremity masses is frequently inconclusive. In 18 patients with normal or nonspecifically abnormal radiographs, gray scale ultrasonography provided useful additional information. ...
Bolus dynamic computed tomography in the evaluation of pulmonary sequestration
(Elsevier, 1987-10)
Three cases of pulmonary sequestration evaluated by bolus dynamic computed tomography are described. The computed tomography appearance and the differential diagnosis are discussed. It is important to recognize the advantages ...
