Evaluation of Diagnostic Value of CT Scan and MRI in Brain Tumors and Comparison with Biopsy
Abstract Background Cerebral neoplasm arises from brain, spinal cord and meningeal cells. Not only malignant cerebral neoplasm also benign tumor could lead to death due to mass effect on vital structures. Access to these tumors is difficult, and MRI and CT scan could be helpful in determining anatomical location of tumors and distinction of malignant from benign. Objective For better and ea...

متن کاملNeuroendocrine Tumors: A Review of CT and MRI Findings
Neuroendocrine tumors, including pancreatic neuroendocrine tumors and carcinoid tumors, are rare neoplasms that arise from a common precursor, the APUD cell (amine precursor uptake and decarboxylation). All neuroendocrine tumors have the ability to produce and secrete peptides and hormones, although many do not. Functional tumors, those that secrete hormones, tend to present early with small tu...
متن کاملCardiac calcified amorphous tumors: CT and MRI findings.
PURPOSE We aimed to evaluate computed tomography (CT) and magnetic resonance imaging (MRI) findings of cardiac calcified amorphous tumors (CATs). METHODS CT and MRI findings of cardiac CATs in 12 patients were included. We retrospectively examined patient demographics, location, size, shape configuration, imaging features, calcification distribution of tumors, and accompanying medical problem...
متن کاملPET and MRI-guided focused ultrasound surgery for hypoxic-tissue ablation combined with radiotherapy in solid tumors
Background: The rationale was to develop an ablation approach to destroy regions of tumor resistant to radiation and thus reduce the time required for whole tumor ablation, while improving overall tumor control after radiotherapy. Materials and Methods: The system is composed of a micro positron emission tomography (mPET), 7T magnetic resonance imaging (MRI), and a customized MRI-compatible foc...
