Cobra-head choledochocele: depiction with computed tomography and cholangiogram

Depiction of celiac ganglia on positron emission tomography and computed tomography in patients with lung cancer.

OBJECTIVE To differentiate imaging characteristics of celiac ganglia from metastatic lesion on positron emission tomography-computed tomography (PET-CT) in patients with lung cancer and correlate these findings to postmortem multidetector row computed tomography (MDCT). METHODS One hundred twenty-nine patients were included. Imaging characteristics and fluorodeoxyglucose (FDG) avidity of the ...

Development of Computed Tomography Head and Body Phantom for Organ Dosimetry

Introduction: Quality assurance in Computed tomography (CT) centers in developing countries are largely hindered by the unavailability of CT phantoms. The development of a local CT phantom for the measurement of organ radiation absorbed dose is therefore requisite. Material and Methods: Local CT phantoms were designed to meet the standard criteria of 32 cm diameter for body, 16 cm diameter for...

Computed Tomography utilization in minor head injury

Results Of the 132 cases referred for CT brain, 109 had a GCS score of less than 13 on initial evaluation. Among 109 cases with MHI, 90 were males and 64 (58.7%) were in the age group of 14-44 years. 78 cases were Road Traffic Accident victims, 17 were assaulted and 14 had history of fall. Twenty six (23.9%) had abnormal CT findings. Skull fracture was the commonest finding (19,17.4%), followed...

Indications for computed tomography in patients with mild head injury.

The factors affecting outcome were analyzed in 1,064 patients, 621 males and 443 females aged 10 to 104 years (mean 46 +/- 23 years), with mild head injury (Glasgow Coma Scale [GCS] score > or =14) but no neurological signs presenting within 6 hours after injury. Intracranial lesion was found in 4.7% (50/1,064), and 0.66% (7/1,064) required surgical treatment. The Japan Coma Scale (JCS) and GCS...
