MR fistulography with percutaneous instillation of aqueous jelly: A cost effective technique innovation.

Background: Perianal fistula is a commonly encountered condition in routine surgical practice. Accurate presurgical mapping of these tracts is vital to prevent recurrence. We have assessed the effectiveness of percutaneous instillation of aqueous jelly prior to magnetic resonance (MR) fistulography.

A Comparative Study of Pituitary Volume Variations in MRI in Acute Onset of Psychiatric Conditions.

Introduction: The growing belief that endocrine abnormalities may underlie many mental conditions has led to increased use of imaging and hormonal assays in patients attending to psychiatric OPDs. People who are in an acute phase of a psychiatric disorder show Hypothalamic Pituitary Adrenal (HPA) axis hyperactivity, but the precise underlying central mechanisms are unclear.

Aim: To assess the pituitary gland volume variations in patients presenting with new onset acute psychiatric illness in comparison with age and gender matched controls by using MRI.

Virtual bronchoscopy in the era of multi-detector computed tomography: Is there any reality?

Virtual bronchoscopy, in conjunction with axial and MPR MDCT images, can enhance diagnostic accuracy of tracheo-bronchial endoluminal pathologies. We describe a few cases highlighting the utility of virtual bronchoscopy in the diagnosis of varied tracheo-bronchial pathologies encountered in the setting of a tertiary care Armed Forces Hospital of India.

High resolution multi detector computed tomography of temporal bone: our experience in a tertiary care service hospital.

High resolution multi detector computed tomography (HRMDCT) is an excellent tool for evaluation of a variety of congenital and acquired conditions affecting the temporal bones. We describe our experience of HRMDCT of temporal bones of 145 patients in a tertiary care and teaching hospital of Armed Forces Medical Services of India over a period of three and half years. Hearing loss was the most frequent indication for HRMDCT and congenital bilateral profound sensorineural hearing loss for evaluation prior to possible cochlear implant formed the single largest group (62, 42%) among all indications for HRMDCT of temporal bones.

Intravenous urography supplemented with computerised tomography urogram: A pragmatic hybrid imaging approach to hydronephrosis.

Background: Image quality in an Intravenous Urogram (IVU) can occasionally be compromised by variables like bowel preparation, renal function and radiographic factors, posing a challenge to all Uroradiologists. The Computerised Tomography Urogram (CTU) yields better diagnostic information than an IVU, due to its inherent superior anatomic delineation and contrast sensitivity, against a trade-off involving radiation dose and cost. Our study was conducted to assess the utility and timing of performing a single-phase CTU, as a problem-solving tool, to clear the diagnostic dilemma in a selected subset of patients, in whom an ongoing IVU could potentially be inconclusive.

Post-prandial paradoxical filling of gall bladder in patients with acute hepatitis: Myth or reality?

Background: A minority of patients of acute hepatitis may exhibit edematous GB walls with no visible lumen despite fasting and may also exhibit paradoxical GB response in the post-prandial state.

Methods: Patients of acute hepatitis underwent routine upper abdominal sonography after overnight fasting. Patients who demonstrated contracted GB with edematous and coapted walls without any visible lumen despite overnight fasting were studied in the post-prandial phase after having breakfast.

Computed tomographic demonstration of unusual ossification of the falx cerebri: a case report.

Bony metaplasia of the falx cerebri is rare in human being. We describe a case of extensive ossification involving anterior half of the falx cerebri in a 47-year-old male. This was detected incidentally during computed tomographic examination of the brain for an unrelated cause.

Splenic artery aneurysm--a rare cause for extrahepatic portal venous obstruction: a case report.

Splenic artery aneurysm is a rare yet very important clinical entity because of its potential for rupture with fatal consequences. Most of the splenic artery aneurysms are found in the middle and distal third of the splenic artery and are usually small (< or = 2 cm) at the time of diagnosis. We describe a rare case of large (5x4 cm) juxta-ostial splenic artery aneurysm causing compression of the splenoportal confluence and adjoining proximal portal vein in a 40-year-old woman.
