Total and visceral adipose-tissue (AT) volumes were determined by computed tomography (CT) by a multiscan technique in 17 men and 10 women with a wide range of body weights. In these primary materials, weight, height, and various diameters, circumferences, and subcutaneous AT thicknesses of the trunk were examined for their relationships to CT-determined(More)
Fifty-one percutaneous fine-needle aspiration biopsies guided by selective angiography and 57 by percutaneous transhepatic cholangiography (PTC) were performed in 88 patients. Fifty-two of the patients had a tumor localized to the pancreas and 19 a tumor of the extrahepatic biliary tract. In 17 patients the suspicion of neoplasia was possible to rule out.(More)
Liver metastases imply a major problem in patients with carcinoid tumors. Patients with localized disease should always undergo resection for cure. Patients with distant metastatic disease can also undergo resection for potential cure or symptom palliation because of the slow growth rate of many carcinoid tumors. In patients with the midgut carcinoid(More)
Eight healthy female volunteers with weights ranging from 46 to 119 kg were examined with a Philips Tomoscan 310 in order to determine the amount of adipose tissue. From analysis of 'attenuation profiles' at the thigh and trunk levels the attenuation interval of adipose tissue was determined to be -190 HU to -30 HU. The adipose tissue volume was calculated(More)
Thrombectomy peformed with the Fogarty balloon catheter may, in a small percentage of cases, given rise to complications. In four cases reviewed, this procedure was associated with aneurysms or arteriovenous fistulae. Careful catheter manipulation and a judicious used of fluoroscopy or angiography during the procedure can reduce the number of such(More)
The adipose tissue volumes of 12 women were determined by computed tomography (CT). Body weight ranged from 46 to 129 kg. Nine or twenty-two transsectional scans were examined with respect to the adipose tissue area. The total adipose tissue volume (ATCT22 or ATCT9) was calculated by assuming linear changes in the adipose tissue area between adjacent scans.(More)
Sixty-four consecutive patients with disseminated midgut carcinoids were treated during an 8-year period according to a single clinical protocol aimed at aggressive tumor reduction by surgery alone or with subsequent hepatic artery embolization. All patients had markedly elevated urinary 5-hydroxyindoleacetic acid (5-HIAA) levels (581 +/- 79 micromol/24 h)(More)
PURPOSE The aim of this study was to evaluate whether lung perfusion scintigraphy (LPS) contributes to the preoperative classification of emphysema heterogeneity in patients undergoing LVRS (lung volume reduction surgery) compared to classification based only on computed tomography (CT). MATERIAL AND METHODS Forty-five potential candidates for LVRS were(More)
Seventeen healthy male volunteers with weights ranging from 54 to 145 kg were examined with a Philips Tomoscan 310. The upper attenuation limit of adipose tissue was determined to be -30 HU. The lower attenuation limit was set to -190 HU. Regional and total adipose tissue volumes were calculated from the adipose tissue areas of 22 scans and from the(More)
Forty-one patients with disseminated midgut carcinoid tumours were treated over a 6-year period according to a strict programme including primary surgical treatment. In 10 patients, a total remission of the disease was obtained. Patients with bilobar hepatic disease had ischaemic treatment of their liver metastases by hepatic arterial embolisation after(More)
