Measurement of dose in panoramic dental radiology.

The National Radiological Protection Board (NRPB) has recommended the introduction of dose-width product (DWP) for the measurement of patient dose in panoramic dental radiology and has proposed a reference level of 65 mGy mm for adult exposures. This paper describes a method for measuring DWP and dose-area product (DAP) using thermoluminescent dosemeters (TLDs). The technique was used on 16 set...

Radiology Rounds - August 2006 - Evaluating Pulmonary Nodules

Increased utilization of chest CT examination has resulted in a dramatic escalation in the number of newly detected solitary pulmonary nodules, defined as round lesions <3 cm in diameter surrounded by lung parenchyma. Although the risk of finding cancer is 3040% in radiographically discovered pulmonary nodules, thin section CT is 10-20 times as sensitive and can detect much smaller nodules. Siz...

Dose-area product measurements in panoramic dental radiology.

In this study, dose-area product (DAP) measurements in panoramic dental radiology have been performed in Germany. The results obtained in this study were proposed as diagnostic reference levels (DRLs). A representative number of dental panoramic units, both with digital and conventional image receptors, have been chosen. Common statistical parameters such as mean, standard deviation and 3rd qua...

Radiology Rounds - September 2006 - Percutaneous Image-Guided Breast Biopsy

Percutaneous image-guided breast biopsies are rapid, minimally invasive procedures that make surgery unnecessary for a large majority (70-80%) of patients whose lesions will prove to be benign. The imageguided biopsies are performed under local anesthetic with no need for conscious sedation using a small incision that requires no stitches to close. The procedures do not deform the breast and ca...
