PURPOSE To compare low-dose spiral computed tomography (CT) with radiography of the chest for the screening and detection of small peripheral lung cancers in a high-risk population. MATERIALS AND METHODS Posteroanterior and lateral radiographs and low-dose spiral CT scans were obtained twice a year from September 1993 to April 1995 in 1,369 individuals (a(More)
PURPOSE Because efficacy of lung cancer screening using chest x-ray is controversial and insufficient, other screening modalities need to be developed. To provide data on screening performance of low-dose helical computed tomography (CT) scanning and its efficacy in terms of survival, a one-arm longitudinal screening project was conducted. PATIENTS AND(More)
Thirty-one patients with hepatocellular carcinoma (HCC) were given either an intraarterial injection of iodized poppyseed oil (Lipiodol) alone (group A, n = 6), an emulsion of iodized oil and doxorubicin hydrochloride (Adriamycin) (group B, n = 15), or chemoembolization with the same emulsion followed by gelatin sponge (Gelfoam) particles (group C, n = 10).(More)
A disintegrin and metalloproteinase (ADAM) represents a protein family possessing both metalloproteinase and disintegrin domains. ADAMTS-1, an ADAM family member cloned from cachexigenic colon adenocarcinoma, is unusual in that it contains thrombospondin type I motifs and anchors to the extracellular matrix. To elucidate the biological role of ADAMTS-1, we(More)
Malignant chest wall tumors are classified into eight main diagnostic categories: muscular, vascular, fibrous and fibrohistiocytic, peripheral nerve, osseous and cartilaginous, adipose, hematologic, and cutaneous. However, there are malignant tumors that arise in the chest wall and that do not fit well in any of these categories (eg, Ewing sarcoma and(More)
Few epidemiologic investigations of visceral adiposity and colorectal neoplasms have attempted the direct quantification of visceral fat. The authors measured visceral fat volume among middle-aged and elderly Japanese men and women who underwent colonoscopy and positron emission tomography/computed tomography for cancer screening in Tokyo, Japan, between(More)
The efficacy of various imaging procedures used for the diagnosis of small hepatocellular carcinomas (HCCs) (lesions no larger than 3 cm in diameter) was evaluated in a retrospective study of 100 patients. Seven patients with hepatic adenomatous hyperplastic nodules containing HCC foci were also assessed. In 89 patients, the lesion was initially detected(More)
PURPOSE To assess the potential value of magnetic resonance (MR) imaging in evaluating pancreatic fibrosis and predicting the development of postoperative pancreatic fistula. MATERIALS AND METHODS This retrospective study had institutional review board approval, and the requirement for informed consent was waived. MR images obtained in 29 consecutive(More)
1. Two restriction fragment length polymorphisms of the human alpha 1a-adrenoceptor gene digested with PstI restriction enzyme exist; the nucleotide change causes the substitution of C residue for T at nucleotide 1441, thereby Arg492 to Cys492 transition, which might confer an additional putative palmitoylation site in the carboxy-terminal segment of the(More)
