99mTc-tetrofosmin SPECT in solitary pulmonary nodule evaluation

Solitary pulmonary nodule evaluation with 99mTc-methoxy isobutyl isonitrile in a tuberculosis-endemic area.

High prevalence of tuberculosis increases the odds for nonmalignant solitary pulmonary nodules (SPNs). Positron emission tomography (PET) using (18)F-fluorodeoxyglucose is the method of choice for the identification of malignant SPNs requiring curative surgery. However, PET is not widely available. Technetium-99m methoxy isobutyl isonitrile (MIBI) is inexpensive, widely available and shows incr...

Evaluation of the solitary pulmonary nodule.

Solitary pulmonary nodules are common radiologic findings, typically discovered incidentally through chest radiography or computed tomography of the neck, chest, and abdomen. Primary care physicians must decide how to pursue an evaluation of a nodule once it has been identified. The differential diagnosis for pulmonary nodules includes benign and malignant causes. Diameter of 8 mm or more, "gro...

Imaging evaluation of the solitary pulmonary nodule.

The solitary pulmonary nodule (SPN) is a common diagnostic problem facing the pulmonologist. The incidence of SPNs is increasing primarily because of the increasing use of multidetector CT scanning for the evaluation of chest disease. This article reviews the radiologic assessment of the SPN, with a focus on thin-section CT, positron emission tomography, and CT-guided transthoracic needle biops...

The Solitary Pulmonary Nodule.

Due to the high etiological diversity and the potential for malignancy, pulmonary nodules represent a clinical challenge, becoming increasingly frequent as the number of CT examinations rises. The topic gains even more importance as clear evidence for the effectiveness of CT screening was provided by the National Lung Screening Trial (NLST). Yet, the results were tempered by the high false-posi...
