Oral Contrast-Enhanced Ct Cholangiography--An Initial Experience, I Naseem, J Rees Jan 2004

Oral Contrast-Enhanced Ct Cholangiography--An Initial Experience, I Naseem, J Rees

Department of Radiology

Objective: To describe our experience of CT (Computed tomographic) Cholangiography examination for detection of choledocholithiasis at the Aga Khan University Hospital (AKUH) Karachi Pakistan.Methods: Seven patients underwent helical CT cholangiography for suspected choledocholithiasis. Iopanoic acid (6 grams) was administered orally 8-12 hours before acquisition of a helical CT cholangiogram. Three-dimensional reconstructions and curved multiplanar reformations were generated from a set of axial source images.Results: Our patients had no adverse reactions to iopanoic acid. The degree of biliary opacification was sufficient to perform three-dimensional and curved planar reformations in 5 patients. In two patients, the biliary tree was not opacified. Both …

Mammographic Criteria For Determining The Diagnostic Value Of Microcalcifications In The Detection Of Early Breast Cancer, M Yunus, N Ahmed, I Masroor, J Yaqoob

Department of Radiology

Objective: To evaluate the importance of microcalcifications in the detection of breast carcinoma in conventional mammography.Methods: This prospective study was carried out at Aga Khan University Hospital (AKUH). Mammograms of 68 patients with microcalcifications were evaluated. Craniocaudal and oblique views of both breasts were acquired on routine basis with cone compression and magnified views when required.Results: Among 68 patients with microcalcifications, 61 (89%) had clustered microcalcifications while 7 patients (10.29%) had scattered microcalcifications. Microcalcifications can occur in benign and malignant diseases. While evaluating clustered microcalcifications, few criteria have been established to determine malignant clustered microcalcifications, these include specific and nonspecific …
