MRI Investigations through special endorectal and endovaginal antennas
 Using an endorectal antenna implies the possibility to obtain high resolution images, focused on target organs like the prostate, the rectum and the cervix. This approach gives the possibility to obtain high resolution images of the prostate, rectum and cervix, as well as the overview of the entire pelvis (the evaluation of the pelvine and retroperitoneal limphadenopaties, as well as of the osseous metastasis of the lumbosacral spine and of the pelvine bones).
Preparation
- You are not allowed to consume food 12 h before the investigation
- Cleaning the colon with preparation substances 24 h before the investigation
- If a clyster is performed 2-3 h before the investigation, there is no need for a diet
Endorectal MR for the prostate
The scanning time for the prostate is aproximately 45-60 minutes, the endorectal tube being kept for only 20 minutes. The endorectal tube is used for the tumoral detection, evaluating its dimension, stadialisation (extracapsular extension, the invasion of the neurovascular package and of the seminal vesicles). The prostate spectroscopy is an investigation method for the metabolic composition of the tumoral formation as well as for the normal prostate. The metabolic composition brings information about the nature of the formation, if it is benignal or malignal, and if it is malignal, it evaluates the degree of tumoral aggression.
All this information is very useful in setting a treatment.
Colorectal antenna MR
The colorectal antenna can independently diagnose or can offer additional details, including the stadialisation of the rectal formations, already diagnosed through other methods. The main advantage of it is the possibility to evaluate the tumoral invasion in the structures of the rectal wall, as well as to visualize the limphonodules from the perirectal fat and the invasion of the mesorectal fascia.
Cervical antenna MR
It is an endovaginal antenna used especially for evaluating the cervix neoplasma. The investigation with this antenna provides information about the tumoral dimension, the extent of it at the parametres level, the vagina, the presence of locoregional adenopaties. This method is the best in evaluating the cervix neoplasma in the early stages. |
