Sensitivity and specificity of Nuclear Magnetic Resonance for the evaluation of myometrial infiltration, cervical stromal invasion and lymph node involvement and their anatopathological correlation in endometrial cancer

As for MRI, it allow the evaluation of loco regional extension, detecting cervical involvement and helping to distinguish primary cervical carcinoma from endometrial carcinoma.It is, therefore, the most important imaging method to establish the pre-surgical staging of endometrial cáncer. 3,4pth of myometrial invasion, local and regional spread, lymph node metastasis, and metastasis to distance. 5,6 ObjectivesTo evaluate the sensitivity and specificity of Nuclear Magnetic Resonance (MRI) for the detection of myometrial invasion, cervical stromal invasion and lymph node involvement and to correlate it with the results of pathology in patients operated on for endometrial cancer at the Gynecology Service of The German Hospital of Buenos Aires. Materials and methodsThe hospital´s computerized medical records and surgical protocols were retrospectively reviewed to determine the characteristics of the study population, the interventions performed, and patients diagnosed with stage I-IV endometrial carcinoma who underwent surgical at Hospital´s Gynecology Department German in the period between January 1, 2010 and December 31, 2020.The results of MRI were reviewed and compared with the pathological results.The MRI of the abdominal and pelvis performed at the German Hospital with a 3-tesla General Electric Architect resonator, with gadolinium and with T1 T2 sequences, diffusion technique and fat suppression.Prior to carrying out the antiperistatical study, fasting for 4 hours, bladder emptying is indicated.With the patient in the supine position.Axial and sagittal slices enhanced in T1 are performed prior to contrast administration, sagittal slices 1 and 2 minutes after contrast administration and axial slices 3 minutes after contrast administration.
