Method for medical imaging of body cavities
The present invention relates to an image enhancing composition for the enhancement of contrast in a body cavity, wherein the viscosity of the composition is between 2000 and 4000 mPa·sec. It also relates to a method for enhancing contrast of an image of a body cavity, which method involves introducing one single small aliquot of an image enhancing composition into the body cavity. In another aspect, the present invention provides a high contrast image of a body cavity obtained by the method of the invention, in particular a 3-dimensional high contrast image.
1. A method of imaging a body cavity, comprising:
(a) introducing into a body cavity an aliquot of echo-lucent image enhancing composition having a pH between 5.5 to 7.5 and a viscosity between 2000 to 4000 mPa·sec at room temperature wherein the composition consists essentially of hydroxyethylcellulose and/or methylcellulose, glycerin and a buffer; and
(b) imaging the body cavity to produce an image.
2. The method according to claim 1 , wherein the composition does not contain particulate material.
3. The method according to claim 1 , wherein the composition is free of disinfectants and anaesthetics.
4. The method according to claim 1 , wherein the imaging is 3-dimensional imaging.
5. The method according to claim 4 , wherein the image is a high contrast 3-dimensional image.
6. The method according to claim 1 , wherein the body cavity is a uterine cavity.
7. The method according to claim 1 , wherein the imaging is ultra-sound imaging.
8. The method according to claim 1 , wherein the imaging is sonohysterography.
