  1. 1. Prof. M.C.Bansal. Founder Principal & Controller; Jhalawar Medical College And Hospital, Jhalawar. Ex . Founder Principal & Controller; Mahatma Gandhi Medical College And Hospital, Sitapura , jaipur.
  2. 2.  MRI is one of the great , clinically very useful modern advances in the field of imaging in medical science.  Radio frequency pulses are directed at living body tissue/ Organ in magnetic field , the tissue emits back(reflected )the modulated radiofrequency signals which are used to construct the image of emitting tissue or organ.  By varying the time of application of radiofrequency pulses and sampling the emitted signals,T1 &T2- weighted images are obtained.
  3. 3.  Different tissues appear with different intensity and brightness in T1 and T2 images.  Depending upon their molecular morphology different tissue emit variable radiofrequency signals—hence different intensity and brightness.  Paramagnetic contrast agents like Gadolinium- DTPA are used for better delineation ( demarcation ) of adjoining tissue / organs.
  4. 4.  Study of normal uterus and adnexa – with aim to have clear image of normal myometrium, endometrium , ovary and follicles within the ovary.  Myoma—to differentiate myoma from adenomyoma.localization of myoma—sub serous/ intra mural or sub mucous.  Adenomyosis---accurate diagnosis.  Congenital uterovaginal anomalies— bicornuate, septate,subseptate , unicornuate, didelphys ,rudimentary horn and vaginal atrasia etc
  5. 5.  Gynaecological cancers--- 1. Cervical cancer –extent of parametrium and pelvic organs , pelvic L.N., Endocervical. 2.Endometrial cancer –Myometrial invasion, downward extension to cervix. 3. ovarian cancer—malignant versus benign mass, ascites , retroperitoneal node > 1cm , Bowel bladder , ano rectal . Parietal peritoneum , liver and or omental metastasis. 4. Pregnancy --- complicated by genital cancers
  6. 6.  MRI is most sensitive for diagnosis of Adenomyosis.  MRI Is more accurate and informative in diagnosis of congenital malformation of genito-urinary tract.  Retroparitoneal lymph node > 1cm can be identified so also such small deposits on bowel / bladder liver can be identified in cases of cancers.  It is more sensitive and accurate tool to assess infiltration of myometrial/ cervical wall, adjoining organs and parametrium --thus helps in pre operative staging of genital carcinomas.  As it is safe in pregnancy –it is useful in diagnosis of obstetrical conditions as well s differentiation of tumors (benign / malignant ) complicating pregnancy.
