Computed tomography scanning

All patients should have a brain computed tomography scan or magnetic resonance imaging scan to differentiate an ischemic stroke from a hemorrhagic stroke, as the treatment... 

Chest x-ray or chest computed tomography scan may reveal infiltrates, atelectasis, bronchiectasis, and mucus plugging. 

Intestinal obstruction may be manifested as meconium ileus, distal intestinal obstruction syndrome, or intussusception on abdominal x-ray or computed tomography scan. Rectal prolapse may be noted on physical exam.

Evaluation Frequent physical examination, complete blood count (CBC), reticulocyte, and urinalysis based on symptomatology, the following may be needed needle aspiration to rule out osteomyelitis, abdominal studies (x-ray, computed tomography scan, etc), liver function tests, bilirubin, culture, and chest x-ray. 

Because contrast studies are expensive, invasive, and technically difficult to perform and evaluate, noninvasive tests (e.g., ultrasonography, computed tomography scans, and the ventilation-perfusion scan) are used frequently for the initial evaluation of patients with suspected VTE. 

Abnormal adrenal anatomy is effectively identified using high-resolution computed tomography scanning and perhaps magnetic resonance imaging.

A 25-year-old woman presents to the emergency department complaining of acute onset of shortness of breath and pleuritic pain. She had been in her usual state of health until 2 days prior when she noted that her left leg was swollen and red. Her only medication was oral contraceptives. Family history was significant for a history of "blood clots" in multiple members of the maternal side of her family. Physical examination demonstrates an anxious woman with stable vital signs. The left lower extremity demonstrates erythema and edema and is tender to touch. Ultrasound reveals a deep vein thrombosis in the left lower extremity chest computed tomography scan confirms the presence of pulmonary emboli. What are the likely risk factors in this woman—hereditary, acquired, or both What therapy is indicated acutely What are the long-term therapy options How long should she be treated Should this individual use oral contraceptives ...

Radiographic imaging studies may include chest x-ray, bone scan, chest and abdominal computed tomography scans, positron emission tomography, ultrasonography, and magnetic resonance imaging.

Secretin and calcium provocation tests have been used in the past to assist in the differential diagnosis of Z-E syn-drome. The secretin test proved the more useful but is little used now with improved computed tomography scanning and the use of somatostatin-receptor imaging using the somatostatin analog octreotide. ° ...

Additional diagnostic steps that can be taken include sigmoidoscopy or colonoscopy examination of the stool for occult blood and ova and parasites complete blood cell count erythrocyte sedimentation rate and serum electrolytes. In some cases, radiographic imaging studies, such as computed tomography scans or barium swallows or enemas, may also be necessary if the findings of the above assessment are not typical for IBS. ...

In the rabbit brain safety study using P(CPP-SA) 50 50 copolymer, even less of an inflammatory reaction was observed, and the polymer was essentially equivalent to Gelfoam [94]. In a similar brain biocompatibility study conducted in monkeys, no abnormalities were noted in the computer tomography scans and magnetic resonance images, nor in the blood chemistry or hematology evaluations [95]. No systemic effects of the implants were observed on histological examinations of any of the tissues tested [96]. No unexpected or untoward reactions to the treatments were observed.
