Objectives: To evaluate the impact of the inclusion of computed tomographic colonography (CTC) involving faecal tagging and no laxatives on the computed tomography (CT) study routinely used in staging patients with colorectal cancer.
Methods: CTC was performed on 25 patients who had a diagnosis of colorectal carcinoma, with pathological correlation. Researchers recorded the accuracy of the CTC for staging colorectal cancer, as well as any changes to the plans for surgery based on this exam.
Objective: Distinct aspects can influence the complication rates of computed tomography-guided percutaneous fine needle aspiration biopsy of lung lesions. The purpose of the current study is to determine the influence of radiological techniques and clinical characteristics in predicting complications from this procedure.
Subjects And Methods: A retrospective study was developed involving 340 patients who were submitted to a consecutive series of 362 computed tomography-guided fine needle aspiration biopsies of lung lesions between July 1996 and June 2004, using 22-gauge needles (CHIBA).
Objective: Computed guided percutaneous biopsy of lung lesions is widely accepted as an effective and safe procedure for specific diagnose. The purpose of this study is to present the experience of an oncology center in the use of computed tomography (CT)-guided cutting needle biopsy as an effective procedure for adequate material and specific diagnose of lung lesions.
Subjects And Methods: This study reports a retrospective analysis of 94 consecutive patients admitted in an oncologic center, reference in Brazil (Hospital do Câncer-AC Camargo), between 1996 and 2004, who were submitted to 97 CT guided cutting needle biopsy of pulmonary lesions.
