Transient Hepatic Attenuation Difference (THAD)– A Case Report

Abstract Transient hepatic attenuation difference (THAD) are areas of increased parenchymal enhancement visible during the hepatic arterial phase on hepatic CT. THADs are associated with a large variety of liver disorders-Portal or hepatic vein thrombosis, cirrhosis, Budd- Chiari syndrome, biliary obstruction, trauma ,focal hepatic lesions and aberrant blood supply. THADs that are associated with hepatic […]

Helical CT evaluation of aortopulmonary window

Abstract Aortopulmonary window is an opening between the aorta and the pulmonary trunk. Two distinct separated semilunar valves must exist to establish the diagnosis of aortopulmonary window, and this defect should be differentiated from truncus arteriosus. Aortopulmonary window is generally diagnosed by echocardiography or Angiocardiography. The authors present two cases of Aortopulmonary window diagnosed by

Kommerell’s Diverticulum and Stenosis of an Aberrant Left Subclavian Artery

Abstract Left aortic arch with an aberrant right subclavian artery is the most common anomaly of the aortic arch. Other rare anomalies include the occurrence of a right aortic arch with an aberrant left subclavian artery that has a diverticulum at its site of origin, known as Kommerell’s diverticulum. Right-sided aortic arch with an aberrant

Giant aneurysm of aortopulmonary collateral.

Introduction We present an unusual case of a giant aneurysm of an aortopulmonary collateral, in a patient of Tetralogy of Fallot with pulmonary atresia on long-term conservative treatment. Aneurysm of aortopulmonary collateral is an extremely rare finding. Only a few similar cases have been reported in literature.

Contrast Material Extravasation:Appearances on Helical Computed Tomography

Abstract Contrast material extravasation on a computed tomography image invariably indicates disruption ofvascular structures, bowel, or the urinary tract. The pattern of contrast material extravasation often allowsexact anatomic localisation of the site of haemorrhage or perforation and contributes to effective intervention.In this pictorial essay, the helical computed tomography appearances of contrast material extravasation arehighlighted with

Magnetic resonance imaging diagnosis of Mayer-Rokitansky-Kuster-Hauser syndrome

Abstract Magnetic resonance imaging (MRI) is the mainstay in the imaging evaluation of Mullerian agenesis, but is not routinely being utilized, particularly in India. Though sagittal MRI clearly demonstrates the absence or hypoplasia of the uterus and the axial images demonstrate the normal ovaries, it is the ability to identify and objectively evaluate other associated

Multi- attribute Non-initializing Texture Reconstruction based ASM (MANTRA)

Abstract In this paper we present MANTRA (Multi-Attribute, Non-Initializing, Texture Reconstruction Based Active Shape Model) which incorporates a number of features that improve on the the popular Active Shape Model (ASM) algorithm. MANTRA has the following advantages over the traditional ASM model. (1) It does not rely on image intensity information alone, as it incorporates
