Avaliação das indicações de ressonância magnética da pelve feminina em um centro de referência oncológico, segundo os critérios do Colégio Americano de Radiologia

OBJETIVO: Comparar as indicacoes de ressonância magnetica da pelve feminina num centro de referencia oncologico. MATERIAIS E METODOS: Estudo retrospectivo, unicentrico, realizado por revisao de prontuarios e laudos de exames de imagem. Foram incluidas 1060 pacientes que realizaram ressonância magnetica da pelve, de janeiro de 2013 a junho de 2014, num centro oncologico. As indicacoes dos exames foram classificadas segundo os criterios do American College of Radiology (ACR). RESULTS: The mean age of the patients was 52.6 ± 14.8 years, and 49.8% were perimenopausal or postmenopausal. The majority (63.9%) had a history of cancer, which was gynecologic in 29.5% and nongynecologic in 34.4%. Of the patients evaluated, 44.0% had clinical complaints, the most common being pelvic pain (in 11.5%) and bleeding (in 9.8%), and 34.7% of patients had previously had abnormal findings on ultrasound. Most (76.7%) of the patients met the criteria for undergoing magnetic resonance imaging, according to the ACR guidelines. The main indications were evaluation of tumor recurrence after surgical resection (in 25.9%); detection and staging of gynecologic neoplasms (in 23.3%); and evaluation of pelvic pain or of a mass (in 17.1%). CONCLUSION: In the majority of the cases evaluated, magnetic resonance imaging was clearly indicated according to the ACR criteria. The main indication was local recurrence after surgical treatment of pelvic malignancies, which is consistent with the routine protocols at cancer centers.
