Accuracy of plain radiographs in diagnosing biopsy-proven malignant bone lesions.

Background: The diagnosis of primary bone tumours is a three-fold approach based on a combination of clinical, radiological and histopathological findings. Radiographs form an integral part in the initial diagnosis, staging and treatment planning for the management of aggressive/malignant bone lesions. Few studies have been performed where the radiologist's interpretation of radiographs is compared with the histopathological diagnosis.

Hybrid imaging using low-dose, localizing computed tomography enhances lesion localization in renal hyperparathyroidism.

Background: Preoperative localization of parathyroid lesions is potentially beneficial in renal patients with hyperparathyroidism. The aim of this study was to determine the localizing value of hybrid single-photon emission computed tomography combined with low-dose x-ray computed tomography (SPECT/LDCT) compared with SPECT alone and whether the LDCT improved reader confidence.

Patients And Methods: A retrospective study examined parathyroid scintigraphy results of patients previously referred with a diagnosis of renal hyperparathyroidism.
