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

CT appearance of the spleen following conservative management of traumatic injury
(Springer-Verlag; American Society of Emergency Radiology, 1999-06)
Objective: To describe the long-term changes in the traumatized spleen following conservative management in pediatric patients. Methods: Between 1991 and 1997, 92 children were imaged with splenic trauma. The study population ...
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 ...
