Detection of small pulmonary nodules using direct digital radiography and picture archiving and communication systems.

Purpose: To evaluate the detection of small pulmonary nodules, in the diameter range of 5.4 to 15 mm, using direct digital chest imaging and soft copy interpretation on picture archiving and communication systems.

Materials And Methods: The results of clinical computed tomography (CT) scans of the thorax were retrospectively reviewed from our radiology information system and picture archiving and communication systems archives.

Reduced radiation for adult thoracic CT: a practical approach.

Purpose: To determine whether radiation dose to patients can be reduced for clinical thoracic CT scans without loss of diagnostic information.

Materials And Methods: One hundred consecutive patients having clinical CT examinations of the thorax were included. The patients were divided into 4 groups, and the mAs setting determined from the patient's weight as follows (max.
