Aim: To present the systematic ultrasonographic assessment in fetal osteochondrodysplasias and to evaluate the fetal MRI intake, as a complementary exploration to US, in the prenatal diagnosis and perinatal prognosis of fetal nonlethal osteochondrodysplasias. Material and methods: In this tertiary multicentre study were included 37 cases diagnosed prenatally with various entities in the category of nonlethal fetal osteochondrodysplasias. The initial diagnosis was carried out by the routine or detailed ultrasound examination. Fetal MRI was accomplished for selected cases.Results: Nonlethal skeletal dysplasia was suspected and then diagnosed after 17 gestational weeks. The suspicion of osteochondrodysplasia as a reference diagnosis element has required systematic and thorough ultrasound examination. Fetal MRI is a valuable exploration, complementary to prenatal ultrasound bringing in very useful details for the diagnosis of osteochondrodysplasias. The global diagnosis of skeletal dysplasia depends to a great extent on the genetic or biochemical abnormality that causes them.Conclusions: US is always the fundamental screening exploration for fetal assessment in nonlethal osteochondrodysplasias. The details brought by the fetal MRI are useful, and the exploration is harmless for the fetus and the mother. Certain diagnosis cannot be accurate and complete without the contribution of genetics, maternal and fetal medicine, obstetrics or radiology. [ABSTRACT FROM AUTHOR]

Aims: The aim of the study was to evaluate the diagnostic ability of sonovaginography (SVG) with ultrasound gel in patients with endometriosis.Material and Methods: We conducted a multicentre prospective study, which included 193 patients with symptoms highly suggestive for endometriosis. All patients were investigated by transvaginal sonography and SVG with gel and afterwards underwent laparoscopic surgery. For each category of endometriotic lesions investigated, we calculated and compared the sensitivity, specificity,  positive predictive value and negative predictive value of the imagisticinvestigations used.Results: In the case of endometriotic lesions of the uterosacral ligaments, SVG with gel had a sensitivity of 78.5% and a specificity of 96% (p=ns). The lesions of the vagina and rectovaginal septum were diagnosed with a sensitivity of 79%, respectively 94% (p=ns), obtaining a specificity of 99%, respectively of 97% (p=0.007). The lesions of the Douglas pouch were identified with a sensitivity of 81% (p=0.015), and those of the rectosigmoid with a 94% sensitivity (p=0.010). We obtained lower sensitivity (67%) in detecting the lesions of the urinary bladder (p=ns).Conclusions: SGV with ultrasound gel represents a useful investigation tool for the evaluation of endometriotic lesions in the posterior pelvic compartment.
