Recent advances in computed tomography (CT) and fiberoptic bronchoscopy (FOB) have led to confusion concerning the optimal use of these modalities, especially with regard to each other. The present review summarizes the current understanding of the role of CT in relation to FOB. Emphasis is placed on optimization of CT technique and basic principles of interpretation of the images. In addition, an in-depth evaluation is presented of the advantages and limitations of CT and FOB in the analysis of both focal and diffuse diseases of the airways and lung parenchyma.

To evaluate the accuracy of magnetic resonance (MR) and ultrasound (US) criteria for breast implant integrity. ⋯ MR imaging depicts implant integrity more accurately than US; neither method reliably depicts minimal leakage with shell collapse. Mammography is useful in screening bilumen implant integrity.

To determine the frequency of unsuspected pelvic fracture and soft-tissue injury in patients referred for magnetic resonance (MR) imaging for possible radiographically occult hip fracture. ⋯ A high prevalence of occult pelvic fracture and soft-tissue injury may be identified with MR studies designed to evaluate occult hip fracture when large-field-of-view T1-weighted coronal sequences are combined with T2-weighted or STIR sequences.

To correlate the histologic structure and echotexture of peripheral nerves and verify if ultrasound (US) findings can be used to differentiate nerve from tendon. ⋯ Peripheral nerves have a typical US pattern that correlates with histologic structure and facilitates differentiation between nerves and tendons.
