To assess the successful eruption of permanent lateral incisor or canine in the bone grafted area. MATERIALS AND METHODS The children age group of 9-21 years with unilateral cleft lip and palate came t...
Bezoars are rare conditions of mechanical intestinal occlusion. Among the various types of bezoars, phytobezoars and trichobezoars are the most common types. Symptoms are usually indistinguishable from other more common entities; therefore, it may be difficult to reach a correct diagnosis. Computed tomography (CT) scan is the preferred diagnostic method. Treatment may include surgery, lavage wi...
UNLABELLED Although unnecessary for children with headache and normal history, computed tomography (CT) scans are widely used. This study sought to determine current practice patterns of neuroimaging to diagnose pediatric headache in a variety of treatment settings and to identify factors associated with increased use of neuroimaging. METHODS This retrospective claims analysis included childr...
conclusions a high index of suspicion is essential for early detection of ddr and dddr. patients with high impact injuries or surrounding organ damage should be followed with serial clinical examinations, follow-up radiologic assessments, and even re-exploration in situations highly suspicious for diaphragmatic injuries. introduction diaphragmatic rupture (dr) is an uncommon, potentially seriou...
Efforts are being made to develop a new type of CT system that can scan volumes over a large range within a short time with thin slice images. One of the most promising approaches is the combination of helical scanning with multi-slice CT, which involves several detector arrays stacked in the z direction. However, the algorithm for image reconstruction remains one of the biggest problems in mul...
Background & Objectives: Computed tomography (CT) represents 11% of all diagnostic radiology procedures but it contributes to almost 67% of the total effective dose to the human population. In head and neck CT which consist of 1/3 of total CT scans, other critical organs such as lenses and thyroid are in the radiation field. Also in the abdomen and pelvis scan, irradiation of ovaries is unavoid...
In our centre, 111 patients have been treated with linear accelerator stereotactic radiosurgery. Angiographic, CT and MRI images are generated and the target coordinates calculated in 3 dimensions. For CT scanning, cross sections of perpendicular and oblique fiducial markers are seen. For follow-up CT scans done without the frame, a virtual frame is generated by means of a computer program that...
