Diagnosis Pitfalls Of Magnetic Resonance Imaging (MRI) Technology In Radiotherapy

Objective:The major advantages of magnetic resonance imaging(MRI)are primarily superior contrast resolution and better soft tissue differentiation.multi-dimensional imaging features.For the diagnosis and staging of some malignant tumors,such as head and neck cancer,rectal cancer,prostate cancer,cervical cancer,etc.,MRI has become the preferred application.However,some diagnosis pitfalls will be presented while MRI is used in the diagnosis and evaluation of tumor,which can directly affect the selection of treatment options and even the prognosis.It's important to avoid these pitfalls in diagnosis of tumor with MRI.Materials and methods:To report three clinical cases from Department of Radiation Oncology of the First Affiliated Hospital of College of Medicine of Zhejiang University,and to study case reports and reviews published,then to give a literature.Results:Although MRI has the incomparable advantage in diagnosis of tumor and radiation therapy,there are some diagnostic pitfalls.such as Magnetic susceptibility artefact with lymphadenopathy,Herpes simplex encephalitis with radioactive brain injury,and yellow-red marrow reconversion with bone metastases,which we should pay special attention to.Conclusions:The major advantages of magnetic resonance imaging(MRI)are primarily superior contrast resolution and better soft tissue differentiation.multi-dimensional imaging features.But radiologists and physicians should still be aware of the possible appearance of pitfalls on MR images to avoid misinterpretation and excessive treatment in clinical diagnosis.
