title: The G-spot: an observational MRI pilot study.
abstract: OBJECTIVE
  To identify a G-spot complex (GSC) in vivo in MRI examinations at 1.5 Tesla field strength.
  
  
  METHODS
  Observational study.
  
  
  METHODS
  Single centre.
  
  
  METHODS
  Twenty-one consecutive patients (January-March 2014).
  
  
  METHODS
  Imaging analysis of routine imaging protocols for usual medical indications with and without concomitant opacification of the vaginal cavity with inert ultrasound gel. The gel distends the otherwise collapsed vaginal walls, allowing for an improved discrimination of anatomic features. The macroscopic and histological results recently derived from the dissections of fresh cadavers by Ostrzenski et al. were translated into imaging characteristics to be expected in the respective MRI sequences (e.g. T1- and T2-weighted) in search of an in vivo correlate of the GSC. Age, menopause status, medical indication and diagnosis were co-variables.
  
  
  METHODS
  To analyse primarily whether MRI imaging is able to depict a distinct morphological entity in vivo matching the GSC, based on anatomical descriptions published recently. The elaboration of an appropriate MRI-imaging protocol was a secondary aim.
  
  
  RESULTS
  A total of 21 studies were obtained. A GSC was identified within the anterior vaginal wall in 13/21 patients (62%). In all, 10/21 (48%) had vaginal gel opacification. We identified a GSC in 10/10 patients (100%) with opacification in all three planes of the T2 images. This was only true for 3/11 cases (27%) without opacification.
  
  
  CONCLUSIONS
  There is evidence for an in vivo morphological correlate to the postmortem anatomical findings of a GSC described by Ostrzenski et al.; its visibility in MRI imaging can be significantly improved with vaginal opacification by ultrasound gel.
  
  
  CONCLUSIONS
  Identification of G-spot by MRI with vaginal gel-opacification in 13/21 patients.
