Superficial temporal artery (STA) based pedicled fascial flap plays a pivotal role in ear reconstruction for microtia patients. There is paucity of literature on the anatomy of the STA in microtia patients. The present study aimed to describe any possible anatomical variations seen in the STA of patients afflicted with microtia. Pre-operative carotid computer tomographic angiography images of p...

A 4-day-old female mildly cyanotic neonate presented clinically with ventral herniation of the heart to the anterior abdominal wall and umbilical defect containing bowel loop (Figure [A] and Movie I in the online-only Data Supplement), raising suspicion of pentalogy of Cantrell. Echocardiogram of the ectopic heart, although technically difficult, revealed overlap of the ascending aorta with sma...

OBJECTIVE Sometimes a vertebral artery (VA) enters the spinal canal via the C1-2 intervertebral space, a variation regarded as a C2 segmental-type VA. This paper describes the anatomy of the C2 segmental-type VA and reviews its clinical importance. METHODS Between March 2014 and November 2015, 3386 patients underwent computed tomographic angiography. I identified C2 segmental-type VAs, associ...

CONTEXT Computed tomographic angiography (CTA) is widely applied in the evaluation of cerebral vessels. Contrast enhancement in cerebral CTA without care or test bolus is not always sufficient for high-quality images. AIMS Evaluation of the possibilities of calculation of scan delay for cerebral CTA in case of subarachnoid hemorrhage (SAH), based on clinical data of a patient and to find out ...

I ncidental findings are an important topic in diagnostic imaging. Because of the comprehensive nature of computed tomography (CT) scanning, incidental findings are seemingly found on almost every CT scan performed for a wide variety of reasons in a radiology department. Many of these incidental findings such as a liver cyst are benign and immediately dismissed. Other findings require more exte...

A 67 yr old female with mitral stenosis presented with an acute haemoptysis caused by the rupture of pulmonary varices. Chest radiography and bronchoscopy showed nonspecific abnormalities. The diagnosis of this rare but potentially lethal complication was made using computed tomographic angiography with three-dimensional volume rendering.

e welcome the interest of Drs. Rapezzi and colleagues in our rticle (1). We did not discuss radionuclide imaging of amyloid ith tracers developed for bone scintigraphy because few data are vailable and because of constraints of space. Bone scintigraphy in myloidosis has been evaluated systematically only in very small eries (2), and there is no evidence as yet for a specific molecular nteractio...
