Proposed program guidelines for pregnant radiology residents: a project supported by the American Association for Women Radiologists and the Association of Program Directors in Radiology.

Rationale And Objectives: Written institutional policies governing radiation exposure and work responsibilities for pregnant radiology residents are not uniform and often are nonexistent. Standardized program guidelines would allow residents and program directors alike to prepare for a resident pregnancy with objectivity and consistency.

Materials And Methods: The American Association for Women Radiologists (AAWR) launched a task force to revisit guidelines for the protection of pregnant residents from radiation exposure during training.

Automated volumetry at CT colonography: a phantom study.

Rationale And Objectives: To assess the performance of a computer-aided detection (CAD) algorithm for measuring polyp-like structures on CT colonography (CTC) images of a phantom.

Materials And Methods: We constructed a Plexiglas phantom to which we affixed a series of idealized Plexiglas polyp-like objects, including spheres and hemispheres. We imaged the phantom in a four-channel detector CT scanner at a 1.
