The role of imaging after surgery is pivotal to drive clinical management of early and/or late onset complications. Most frequently used imaging technique after pelvic surgery is Ultrasound (US), Magnetic Resonance Imaging (MRI) and Computed Tomography (CT). While Ultrasound is a standard procedure, using grey scale and/or colour Doppler evaluation, MRI and CT scan protocols should be derived on the basis of the specific indication of the exam. Correct evaluation of female pelvis after gynaecologic surgery, having in mind the most frequent complications, is based on the correct use of the instruments and on the experience of the examiner, who should be aware of the history of the patient, type of surgery and clinical symptoms for which the exam is required; the clinician should be aware of the possibilities and limits of the different techniques, in order to choose the most appropriate imaging modality and promptly make a correct diagnosis...

Magnetic resonance imaging (MRI) is often "one stop shop" for evaluating female pelvic masses that helps in diagnosis, staging, and restaging of these tumors. A pelvic mass can arise from any tissue present within the pelvis. Although most masses in the female pelvis arise from the reproductive organs, masses may also arise from the gastrointestinal tract, urinary system, adjacent soft tissues, peritoneum, etc. It may not always be possible to determine the site of origin or distinguish these masses based on imaging characteristics...

INTRODUCTION: Carcinoma cervix is widely prevalent among women in developing countries. Post contrast Magnetic Resonance Imaging (MRI) utilising spin echo T1 weighted sequence with fat suppression is widely practiced as part of evaluation of carcinoma cervix. However, it is unclear if such post contrast imaging provides any additional information other than adding to the cost of imaging. AIM: To find accuracy of T1 and T2 weighted non contrast MRI protocol in comparison with post contrast spin echo T1 weighted fat suppressed imaging in evaluating the local extent of the carcinoma cervix...

INTRODUCTION: Although salvage radiotherapy (SRT) for PSA recurrence after radical prostatectomy provides better oncological outcomes when delivered early, in the absence of detectable disease many patients are treated for macroscopic locally recurrent tumors. Due to limited data from prospective studies, we hypothesized an important variability in the SRT management of these patients. Our aim was to investigate current practice patterns of SRT for local macroscopic recurrence after radical prostatectomy...

Piriformis muscle syndrome (PMS) is difficult to diagnose by objective evaluation of sciatic nerve injury. Here we report a case of PMS diagnosed by diffusion tensor imaging (DTI) and tractography of the sciatic nerve, which can assess and visualize the extent of nerve injury. The patient was a 53-year-old man with a 2-year history of continuous pain and numbness in the left leg. His symptoms worsened when sitting. Physical examination, including sensorimotor neurologic tests, the deep tendon reflex test, and the straight leg raise test, revealed no specific findings...

We provide an overview of advanced imaging techniques currently being explored to gain greater understanding of the complexity of stress urinary incontinence (SUI) through better definition of structural anatomic data. Two methods of imaging and analysis are detailed for SUI with or without prolapse: 1) open magnetic resonance imaging (MRI) with or without the use of reference lines; and 2) 3D reconstruction of the pelvis using MRI. An additional innovative method of assessment includes the use of near infrared spectroscopy (NIRS), which uses non-invasive photonics in a vaginal speculum to objectively evaluate pelvic floor muscle (PFM) function as it relates to SUI pathology...

In pelvic organ prolapse (POP), the organs are pushed downward along the lines of gravity, so measurements along this longitudinal body axis are desirable. We propose a universally applicable 3D coordinate system that corrects for changes in pelvic inclination and that allows the localization of any point in the pelvis at rest or under dynamic conditions on magnetic resonance images (MRI) of pelvic floor disorders in a scanner- and software independent manner. The proposed 3D coordinate system called 3D Pelvic Inclination Correction System (PICS) is constructed utilizing four bony landmark points, with the origin set at the inferior pubic point, and three additional points at the sacrum (sacrococcygeal joint) and both ischial spines, which are clearly visible on MRI images...

BACKGROUND: Congenital scoliosis is one of the 'difficult to treat' scenarios which a spine surgeon has to face. Multiple factors including the age of child at presentation, no definite pattern of deformity and associated anomalies hinder the execution of the ideal treatment plan. All patients of congenital scoliosis need to be investigated in detail. X rays and MRI of spine is usually ordered first. Screening investigations to rule out VACTERL (Visceral, Anorectal, Cardiac, Tracheo-esophageal fistula, Renal and Lung) abnormalities are required...

Because of the increasing trend of body contour enhancements with injections, implants, and fillers, clinicians should be on high alert for the possibility of silicone-induced hypercalcemia as one of the differential diagnoses in a patient with history of silicone use. Hypercalcemia as a result of silicone injections has been reported, and there is concern that there will be more cases given the popularity of cosmetic silicone. Cases involved a mother and daughter (70 & 55 years) who presented in 2013 with hypercalcemia after cosmetic silicone injections in 2007...
