To evaluate the efficacy of intraparenchymal brain tumor biopsy using endoscopy and a navigation system (navigation-guided endoscopic biopsy) as a diagnostic tool, a case series of intraparenchymal tumor biopsies was reviewed. Navigation-guided endoscopic biopsy was applied in 9 cases, stereotactic needle biopsy in 16 cases, and open biopsy with or without navigation system in 34 cases. In all ...

MRI-targeted biopsy of the prostate appears to have the potential to reduce the high rates of underdiagnosis and overdiagnosis associated with the current diagnostic standard of transrectal ultrasound guided systematic biopsy. Direct or "in bore" MRI-guided biopsy is one of the three methods for MRI-targeted core needle sampling of suspicious, generally Pi-RADS 4 or 5, foci within the prostate,...

Transthoracic image guided biopsy is now firmly established in the armamentarium of diagnostic tests to establish the nature of a mass in the lung, pleura, mediastinum or chest wall. It may be performed under computed tomographic, ultrasonic or fluoroscopic control, and provided a fine needle technique is employed, morbidity is low. Worldwide reports show a 90% true positive yield and a false p...

conclusions the best balance between detection rate of prostate cancer and infectious complications of biopsies achieved in twelve-core biopsy protocol. twelve-core biopsy enhances the rate of prostate cancer detection with minimum adverse effects. patients and materials transrectal ultrasonography (trus) guided biopsy was performed in 180 patients suspicious for prostate cancer due to either a...

Transrectal ultrasonography (US)-guided biopsy is the standard approach for histopathologic diagnosis of prostate cancer. However, this technique has multiple limitations owing to the operator's inability in most cases to directly visualize and target prostate lesions. Magnetic resonance (MR) imaging of the prostate overcomes many of these limitations by directly depicting areas of abnormality ...

Molecular imaging, using positron emission tomography (PET), has become an integral step in the evaluation of many patients with malignancy. However, its use in patients with breast cancer has been limited by the lower levels of (18) F-fluorodeoxyglucose (FDG) uptake in some breast malignancies compared to other cancers, the small size of many breast cancers, and the need for biopsy under PET g...

ectopic thyroid tissue (ett) is a rare entity and a challenging differential diagnosis. this is a report of a case of a mediastinal mass that was found to be an ectopic mediastinal thyroid tissue, in a 77-year-old woman who was admitted to our hospital for breast cancer management. the mediastinal mass was identified in the postsurgical computed tomography (ct) scan of the chest and was suspect...

Image-guided procedures, such as computed tomography (CT)-guided stereotactic and ultrasound-guided methods, can assist neurosurgeons in localizing the relevant pathology. The characteristics of image-guided procedures are important for their appropriate use, especially in brain biopsy. This study reviewed the results of various image-guided brain biopsies to ascertain the advantages and disadv...
