Abstract

Volume reduction surgery has recently been an important surgical procedure for patients with severe pulmonary emphysema. We compared the sagittal and coronal images taken by the HASTE sequence with those obtained by turbo FLASH during deep breathing and with CT images obtained under deep inspiration. Clear images were obtained from both sequences, without cardiac or respiratory motion artifacts. The emphysematous areas were demonstrated as low signal intensity areas, as in CT images. The ratio of signal intensity in the expiratory phase to that in the inspiratory phase was lower than that of volunteers in the HASTE sequence. The HASTE sequence provides useful information about respiratory movement as well as about changes in the pulmonary parenchyma when used for preoperative examination.

Abstract

Three-Dimensional MR angiography (3D-MRA) of the lung was performed in 5 healthy volunteers and 14 patients with primary pulmonary cancer in the hilum, and compared with 2D-MRA. As 3D-MRA could be obtained with single breath holding after intravenous bolus injection of Gd-DTPA, pulmonary vessels of the hilum and peripheral zone were demonstrated more definitely than those of 2D-MRA. In all patients except one case, the relation between the tumor and pulmonary vessels was visualized more clearly by 3D-MRA than 2D-MRA. This technique is considered a non-invasive and effective method for evaluation of pulmonary vessels in the patient with hilar tumor.

Abstract

The mechanism of 201Tl chloride accumulation is unclear in thyroid gland and thyroid tumor. This report examines 108 patients that received thyroid scintigraphy examinations with both 201Tl chloride and sodium 131I. The patients were diagnosed clinically and histologically whenever possible. The ROI were obtained by subtraction imaging with both isotopes and by subtraction positive and negative areas of imaging. Dynamic curves were obtained for 201Tl chloride per square unit of each ROI. The dynamic curve in the radioiodide-accumulated area was examined. The data indicate that the clearance rate of 201Tl chloride (T15) was correlated with the sodium 131I uptake rate at 24 h (r = 0.70).
