 Hello everyone. I am Priyanka. I am a video geologist at Melvin. I am going to be speaking to you about the role of MRI in female pelvic diseases. And this is done as a series of lectures. In this first talk, I will just talk about the basic principles of MRI and its application in the field of pelvic diseases. I have split this talk to simplify. And we will talk about when, by and how do we do MRI of the pelvis. In younger women, MRI is performed to assess for a new pelvic to gentler amnesty. In women of reproductive age group, it is done for diagnoses or phantom illnesses in taking planning of inline myocardial diseases. Immutriosis and its staging. Staging of malignancies. This is the main stage of MRI. And follow-up of disease process. Why? We all know the part superior soft tissue contrast that we get with MRI. It is much better than any other imaging modality of radiology. It also allows for multi-planar assessment of zonal pelvic anatomy. When we add functional study with precision and decision imaging the MRI does allow us to identify a disease process as being benign or malignant. And this is by allowing the estimation of microvascular characteristics of that particular pathology and its cellularity. In terms of patient preparation, it is highly recommended that a patient is fasting for about 3 to 6 hours prior to this plan. Now this reduces the bowel motion of the parts. For the same purpose, it is also recommended to administer an anti-peristaltic agent such as bascopane or clickable. Adding fat saturation plans to the anterior abdomen wall also helps in eliminating emotional audit parts from the anterior tumble. Patients should empty the bladder about an hour before this canal. Now if the bladder is too full, it degrades the deteriorated images by producing audit mass. Whereas if the bladder is very empty, they are going to have a limitation that sometimes there is a movement of the bladder in pelvic abnormalities and you will not be able to assess that. This is do-administer vaginal germ, about 20 cc of this. It is going to be very helpful in this disease such as tumor extending into the vagina or congenital anemones of the vaginal ovaries even in endometriosis. Scheduling of exam according to the menstrual cycle is not really necessary. Also because it delays the scan and the diagnosis thereby dealing with treatment causes for patients who do have malignancy. But it is very useful to get information on patients' LMP in hormone replacement therapy that she is on and if the patient has an agonomy plan surgery. Now these are the sequences that are recommended. See most of these are T2-weighted sequences which is simply because of the far superior zonal anatomy assessment that we get with T2-weighted sequences. In addition, DWI is recommended in one or two prints with at least two B-runs. Ideally obtaining an axonal DWI is more helpful which is in along the cranioconal axis of the body and that helps to reduce the artifacts compared to oblique stans. T1-weighted sequence is quite helpful to identify first eye of hemorrhage or endometriotic deposits. Ideally the size thickness should be 3 mm or less. Now adding a coronal T2-weighted sequence for marine hyaluron after a few B-runs is going to help us look for lymph nodes or any hydrodynamic process which is very important in diagnosis of pelvic tumors and if there is any presence of polymetastasis. Now coming to staging of the pelvic malignancies recently Sego underwent revision in 2018 and it incorporated a staging based on pathological findings when they were available. It is for this purpose that MRI is recommended now to be performed for uterine and cervical cancers so that patient is assigned an appropriate tumor stage which helps to tailor the treatment for her. Now MRI also helps to assess the tumor size, any hyaluronation, any pelvic site validation or lymph node inhalation and all these are important in staging the tumor and in propagating the patient. This also is very very important in fertility spreading surgery which is considered in some patients with cervical cancers who are young and we will be talking about this in the subsequent lecture. I hope you've enjoyed this.
