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 …

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 …

Objective: To determine the incidence of secondary signs of obstruction in patients with ureteral stones on unenhanced helical CT scans.MATERIAL AND Methods: Three hundred consecutive patients with suspected renal colic referred by the emergency department for an unenhanced helical CT scan were evaluated. One hundred and thirty two patients with ureteric calculi were viewed prospectively for the secondary signs of obstruction, which include hydronephrosis, hydroureter, perinephric stranding, nephromegaly, periureteral edema and difference in attenuation between acutely obstructed kidney and unobstructed kidney.Results: In the evaluated 132 patients, calculi were present in the proximal, mid and distal ureter in 12, 18 and …

Objective: To determine the role of helical C.T. scan in the diagnosis of pulmonary embolism.SETTING: Radiology department, Aga Khan University Hospital. One year prospective study May 2001 to May 2002.Methods: Sixty patients suspected of having pulmonary embolism were included in this study. Helical C.T. scan chest was performed from aortic arch to lung bases with intravenous contrast medium. Images were acquired in mediastinal and lung windows. Image interpretation was performed on the console and hard copies for main branch and segmental thrombus.Results: Fifteen patients were diagnosed of having pulmonary embolism on C.T. scan. Clinical correlation and follow up with pulmonary …

Section of Neurosurgery
Objective: To ascertain the efficacy of stereotactic radiosurgery (gamma knife) for the control of glomus jugulare tumours.
Method: Between March 1994 and December 1997 we treated eight patients of glomus jugulare tumour with radiosurgery. These patients have been followed for more than four years (range 52 to 97 months). The age of the patients ranged between 32-64 years (mean 53 years). The male: female ratio was 3:5. Three patients had previously undergone surgery and one had unsuccessful embolization. The dose applied to tumour margin ranged between 16-25 Gy (median 25 Gy). Patients were followed up with yearly MRI scans and …

Objective: To evaluate the safety, efficacy and complications of percutaneous gastrostomy catheter placementunder flouro guidance for long-term enteral feeding.MATERIALS AND Methods: Between April 1998 to May 2002, 23 patients who had percutaneous gastrostomy catheter placement were retrospectively reviewed. Clinical indications for catheter placement included patients with neurologic disease, head and neck malignancy, and pulmonary disease patients. Placement of 12 - 14 Fr gastrostomy catheter was then accomplished with the Seldinger technique. The technical success, procedural complications were recorded.Results: Twenty seven procedures, including revisions, were performed. The success rate for catheter placement was 100%. Revision was necessary in 7 (30%) instances …
