Between 2003 and 2008, 200 consecutive patients with brain metastases treated with Gamma Knife radiosurgery (GKRS) using either 1.5?T or 3.0?T MRI for radiosurgical treatment planning were retrospectively analysed. The number of previously undetected metastases at time of radiosurgery, distant brain failures, time delay to whole brain radiotherapy (WBRT), overall survival and likelihood of neurological death were determined. https://www.selleck.cn/products/blu9931.html Additional metastases were detected in 31.3% and 24.5% of patients at time of radiosurgery with 3.0?T and 1.5?T MRI, respectively (P?=?0.27). Patients with multiple metastases at diagnostic scan were more likely to have additional metastases detected by 3.0?T MRI (P? https://www.selleckchem.com/products/gsk1120212-jtp-74057.html GKRS did not appear to affect the likelihood of distant brain failure, the need for WBRT or the likelihood of neurological death in this series. ""Cardiac anatomic variants, vascular abnormalities and non-neoplastic mass lesions may be misinterpreted as tumours, potentially leading to inappropriate intervention. This article discusses the complementary role of multi-detector computed tomography and magnetic resonance imaging in the work-up of suspected masses. The cross-sectional imaging appearance of common or distinctive anatomic variants and pseudotumours, including ��don't touch�� lesions, are reviewed. Anatomic variants and pseudotumours can potentially be misinterpreted as cardiac tumours. This may cause significant morbidity or mortality if a benign finding or anatomic variant is mistaken for a pathologic or aggressive lesion, triggering inappropriate intervention. In particular, differentiation between thrombus and neoplasm is vital, as well as identification https://www.selleckchem.com/products/Bortezomib.html of lesions that are best left alone. Echocardiography, with high axial spatial resolution and real-time capabilities, is often the means by which unsuspected mass lesions are first discovered. However, it is highly operator dependent, and restrictions in the acoustic window may limit visualisation of some structures.[1] Therefore, computed tomography (CT) and magnetic resonance imaging (MRI) are increasingly being used to differentiate pseudotumours from true neoplasms. This pictorial essay reviews the strengths and weaknesses of CT and MRI in the evaluation of suspected cardiac mass lesions.
