ISBN , Authored by some of the world's preeminent authorities in its field, this new book represents today's best single source of guidance on gynecological imaging!. I give Friend Diagnostic Imaging: Gynecology, 2nd Edition 2e original pdf. Wish you had a great experience with books. And you have more useful knowledge.
In conclusion, MRI has unique qualities which have great potential value in obstetrics and gynaecology.
It will not replace ultrasound in obstetrics but will be of help in those specific situations where ultrasound has known limitations. In gynaecology, it is of value in staging gynaecological tumours and in assessing endometrial changes in the normal cycle. Comparative study of conventional and MRI pelvimetry.

Background Acute abdomen is defined as a sudden onset of abdominal pain, most commonly followed by tenderness or defans of muscular wall, which in most cases require emergency surgical treatment. Causes of acute abdomen are numerous, and they can be divided into three main groups: 1.
Due to close anatomic and physiologic relations, acute gynecological disorders are often mistaken and rather hard to differentiate from other causes of acute abdomen, as they have very similar presentation. Moreover, these diseases are commonly overlapping. As these conditions are usually quite serious and life threatening, proper and fast diagnosis is essential in order to provide patients with the most appropriate treatment. Therefore, radiologist should be familiar with all gynecological conditions which can cause acute abdomen, especially in women in fertile period, and their presentation on different imaging modalities.
Findings and procedure details Ultrasound US is the first-line diagnostic tool for patients with acute abdomen suspected to be caused by gynecological conditions, although with significant limitations. At emergency department, radiologists most often perform transabdominal ultrasonography, which is operator- dependent, and provides insufficient information in cases of obesity or meteorismus. Therefore, gynecological disorders are increasingly diagnosed by computed tomography CT due to better accessibility and better diagnostic capability, as well as possibility of employment of CT guided percutaneous therapy.
Magnetic resonance MR has the highest sensitivity and specificity, and is well suited for young patients, especially pregnant ones, as it avoids radiation. However, due to its price and unavailability, as well as the duration of the examination, it is utilized only when other imaging modalities cannot yield proper diagnosis.
Most common gynecological disorders causing acute abdomen are extrauterine pregnancy, inflammatory disorders- most commonly arising from ovaries and Fallopian tubes, ovarian cysts, ovarian torsion and ischemia, postoperative complications, Page 2 of 23 endometriosis, ovarian hyperstimulating syndrome as a complication of infertility treatment, tumors, thrombosis, congenital anomalies and complications caused by them, pelvic congestion and many others. Extrauterine pregnancy is most often tubal, although implantation of the fertilized egg can occur anywhere in pelvis and abdomen.
Ultrasonographically, amorphous or ring- like mass is seen separate from ovary, in some cases with detectable cardiac activity of embryonic pole. Color Doppler can aid localizing the ectopic pregnancy. On CT, a heterogeneous adnexal mass separate from ovary is observed.
Blood is usually detected both by US and CT, while large amount of ascites is strongly indicative of a a rupture. Ectopic pregnancy is the leading cause of hydrosalpinx, and therefore should always be considered in cases of its detection.
Inflammation usually arises from Fallopian tubes and ovaries in form of salpingitis, which can evolve into hydrosalpinx, pyosalpinx or tubo-ovarian abscess or pelvic inflammatory disease PID. Imaging findings can be normal in early stages, while later dilated, fluid filled Fallopian tube is observed.
US is not very specific in distinguishing dilated tubed from other pelvic cystic lesions or fluid collections. CT demonstrates dilated, fluid filled tubular structures with enhancing walls, distinguished from dilated bowel loops by the absence of per os ingested contrast agent.
Tubo-ovarian abscess is characterized by complex fluid collections, with thickened, irregular wall which is contrast enhanced, band like infiltrates and imbibition of parapelvic fat tissue and thickening of uterosacral ligament. Displacement of lig. However, common pitfalls include increased FDG uptake in normal ovaries during ovulation, as well as normal physiologic activity in bowel, endometrium, and blood vessels, focal retained activity in ureters, bladder diverticula, pelvic kidneys, and urinary diversions[ 3—5 ].
Magnetic resonance imaging in obstetrics and gynaecology
Ideally, the bladder should be empty to avoid artefacts on PET images from high radioactivity concentration in the bladder. It is suggested that the patient is scanned in a caudal to cranial direction, thus imaging the pelvis at the beginning of the study. Pelvic imaging can be improved by intravenous injection of a diuretic agent to reduce tracer retention in the urinary system.
A technique of hydration, diuretic administration and pre-imaging voiding obviates the need for invasive procedures such as bladder drainage in most cases.
Never Miss an Issue
Bowel preparation can be performed with oral hydration as well and some groups recommend the use of oral contrast[ 5 ]. The administration of butylscopolamine 20—40 mg at the time of FDG injection has been reported to reduce FDG uptake in the bowel[ 6 ].Br J Obstet Gynaecol ; Br J Obstet Gynaecol ; Torsion of ovary and surrounding tissue around vascular pendulum can occur at normal ovaries of prepuberty girls, as well as pregnant and post-menopausal women, due to hypermobility of the ovary or adnexal lesion.
This article reviews the literature that provides the evidence for the use of FDG-PET in gynaecological malignancies, identifies areas of real benefit and future potential, and highlights circumstances where there is limited value.
