Final diagnosis is made by laparoscopy, but can also be helped by imaging. Most endometrial deposits are found in the pelvis (ovaries, peritoneum, uterosacral ligaments, pouch of Douglas, and rectovaginal septum). Extra pelvic deposits, including those in the umbilicus and diaphragm, are rare. Endometriomas are cysts of endometriosis within the ovary. Endometrial implants are responsible of pelvic adhesions or visceral infiltration. Consequences of these disease are often severe, from pelvic chronic pain until ureteral or rectal invasion. Diagnosis is difficult. Ultrasonography is able to detect ovarian endometriomas or adenomyosis but can not detect deep posterior endometriosis. MRI. is actually the more accurate examination for diagnosis and presurgical staging for endometriosis. Nevertheless, the knowledge of MRI technical parameters, and rules of interpretation are necessary for diagnosis accuracy, due to difficulty to detect the lesions. In this review, we will successively describe endometriosis physiopathology and imaging with different locations, with a particular attention to MRI, in order to allow adequate diagnosis and staging.</p></div>","PeriodicalId":100447,"journal":{"name":"EMC - Radiologie","volume":"1 1","pages":"Pages 36-49"},"PeriodicalIF":0.0,"publicationDate":"2004-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.emcrad.2003.10.001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75510141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The acquisition is peformed by a set of detector fitted on a ring. The detector is based on a scintillator chosen in order to optimize the efficiency and the signal to noise ratio. Coincidence detection is dedicated to measure the two 511 keV photons resulting from the annihilation of the positron. Tomographic slices are reconstructed thanks to sophisticated algorithms adapted to the tri dimension acquisitions. The quantification of PET images is achieved by the correction of the main physical effects that alter the detection process. For the patient, the effectives doses resulting for a PET examination is about 8 mSv. The installation of a PET device requires specific investments to ensure the radioprotection of the staff. The PET evolution is very fast, this is particularly important for the detectors and for the algorithms. Recently, a new generation of PET/CT devices has been developed to benefit of the complimentarity of both modalities. The CT images can be used for attenuation correction, to localize the lesion detected by PET and to optimize the therapeutical procedures. Thanks to all these developments, PET is a powerful diagnostic tool among the other medical imaging modalities.</p></div>","PeriodicalId":100447,"journal":{"name":"EMC - Radiologie","volume":"1 1","pages":"Pages 2-35"},"PeriodicalIF":0.0,"publicationDate":"2004-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.emcrad.2003.12.001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81383318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
