; MRI scan non-ionizing imaging modality; body part under investigation is subjected to electromagnetic pulses (hydrogen ions and protons align and emit detectable radio waves), building a tissue 'picture' in 3- or 5-mm-wide sections
  • T1-weighted (T1-W) MRI fat-containing tissues show as white; water-containing tissues show as dark areas

Patient discussion about MRI scan

Q. Anybody to tell me more about MRI scan? had an MRIscan and this has snown adenocarcinoma of endometrium early stage There is no lymphatic involvement but is it possible an MRIscan to miss some tumor?

A. MRI is a very effective machine but it has it's limits. it has a great resolution but will not see very small tumors. therefore- it can miss metastasis sometime. but if your adenocarcinoma is in early stage- it might not sent metastasis. they did a biopsy? that can give you some idea what to expect.
