The Radiology Assistant : Bone tumors - Differential diagnosis
2010年4月10日 · The most reliable indicator in determining whether these lesions are benign or malignant is the zone of transition between the lesion and the adjacent normal bone (1). Once we have decided whether a bone lesion is sclerotic or osteolytic and whether it has a well-defined or ill-defined margins, the next question should be: how old is the patient?
An Approach to the Evaluation of Incidentally Identified Bone Lesions ...
2017年4月24日 · For indeterminant lesions, MRI is the most helpful next step in local characterization. An MRI feature that can be helpful in excluding malignancy in a bone lesion is the identification of macroscopic fat, a finding that carries with it …

2022年11月24日 · Low T1 bone lesions or T1 hypointense bone lesions are radiological terms to categorise bone lesions according to their visually perceived low signal on T1 weighted images.
The role of magnetic resonance imaging in the evaluation of bone ...
Bone tumours and tumour-like lesions are frequently encountered by radiologists. Although radiographs are the primary screening technique, magnetic resonance imaging (MRI) can help narrow the differential or make a specific diagnosis when a lesion is indeterminate or shows signs of aggressiveness.
Magnetic Resonance Imaging of Benign Bone Lesions: Cysts …
Magnetic resonance imaging is considered the modality of choice for evaluation of other benign musculoskeletal lesions because it is highly sensitive to changes in the signal intensity of bone marrow and adjacent soft tissues.
MRI of bone tumors: advances in diagnosis and treatment …
MRI is a unique imaging technique that allows direct visualization of bone marrow with high spatial resolution and is considered the best tool for local staging of bone tumors. Owing to its high natural contrast resolution, it can depict specific tissue components useful for tumor characterization.
Diagnosis of Bone Tumors: Radiologic and Pathologic Approach
2016年6月1日 · Computed tomography (CT) and magnetic resonance imaging (MRI) are indispensable in tumor staging for the following reasons: (1) their multiplanar capacities and outstanding soft-tissue contrast; (2) their ability to ascertain, with great accuracy, the tumor size, configuration, and location; (3) their capability in showing the intramedullary ...
