NEEDLE GUIDANCE FOR MOLECULAR IMAGING
A system and method for biopsy or other needle guidance procedures for molecular imaging. A molecular imaging system having one or more radiation detectors for scanning tissue within a region of interest is provided, as well as a hollow needle for performing a medical procedure on the tissue, and a radioisotope in substantially liquid form. The radioisotope is introduced into the lumen of the needle, and the radiation emitted from the radioisotope contained in the needle lumen is detected using the molecular imaging system so that the needle can be guided into the region of interest.
1 . A method for needle guidance in molecular imaging, comprising the steps of:
providing a molecular imaging system having one or more radiation detectors for detecting radiation emitted from tissue of a patient within a region of interest, a hollow needle for performing a medical procedure on the tissue, and a radioisotope in substantially liquid form;
introducing the radioisotope into a lumen of the needle; and
detecting radiation emitted from the radioisotope contained in the lumen of the needle using the molecular imaging system.
2 . A method according to claim 1 , further comprising the step of injecting the radioisotope into the patient.
3 . A method according to claim 2 , further comprising the step of detecting radiation emitted from the radioisotope contained in the tissue within the region of interest using the molecular imaging system.
4 . A method according to claim 3 , wherein the molecular imaging system includes a display, and further comprising the step of displaying a combined image of the radiation detected from the radioisotope contained in the needle and in the patient tissue.
5 . A method according to claim 4 , further comprising the step of guiding the needle to perform the medical procedure on the tissue by using the combined image or the radiation detected from the radioisotope contained in the needle.
6 . A method according to claim 1 , wherein the medical procedure is a biopsy.
7 . A method according to claim 1 , wherein the medical procedure is an injection of medication or the implantation or extraction of markers or radiotherapy seeds
8 . A method according to claim 1 , wherein the region of interest is one or both breasts.
9 . A method according to claim 1 , further comprising the steps of determining whether the tip of the lumen is displayed on the display, and if not, then filling in the tip of the lumen on the display.
10 . A method for needle guidance in molecular imaging, comprising the steps of:
providing a molecular imaging system having one or more radiation detectors and a display for displaying a functional image of tissue of a patient within a region of interest, a hollow needle for performing a medical procedure on the tissue, and a radioisotope in substantially liquid form;
injecting the radioisotope into the patient;
introducing the radioisotope into the lumen of the needle;
detecting radiation emitted from the radioisotope contained in the lumen of the needle and in the tissue within the region of interest using the molecular imaging system; and
displaying a combined image of the radiation detected from the radioisotope contained in the needle and in the patient tissue.
11 . A method according to claim 10 , further comprising the step of guiding the needle to perform the medical procedure on the tissue by using the combined image or the radiation detected from the radioisotope contained in the needle.
12 . A method according to claim 11 , wherein the medical procedure is a biopsy.
13 . A method according to claim 10 , wherein the medical procedure is an injection of medication or the implantation or extraction of markers or radiotherapy seeds
14 . A method according to claim 10 , wherein the region of interest is one or both breasts.
15 . A method according to claim 10 , further comprising the steps of determining whether the tip of the lumen is displayed on the display, and if not, then filling in the tip of the lumen on the display.
16 . A method for needle guidance in molecular imaging, comprising the steps of:
providing a molecular imaging system having one or more radiation detectors and a display for displaying a functional image of tissue of a patient within a region of interest, a hollow needle for performing a medical procedure on the tissue, and a radioisotope in substantially liquid form;
injecting the radioisotope into the patient;
introducing the radioisotope into the lumen of the needle;
detecting radiation emitted from the radioisotope contained in the lumen of the needle and in the tissue within the region of interest using the molecular imaging system;
displaying a combined image of the radiation detected from the radioisotope contained in the needle and in the patient tissue; and
guiding the needle to perform the medical procedure on the tissue by using the combined image or the radiation detected from the radioisotope contained in the needle.
17 . A method according to claim 16 , wherein the medical procedure is a biopsy.
18 . A method according to claim 16 , wherein the medical procedure is an injection of medication or the implantation or extraction of markers or radiotherapy seeds
19 . A method according to claim 16 , wherein the region of interest is one or both breasts.
20 . A method according to claim 16 , further comprising the steps of determining whether the tip of the lumen is displayed on the display, and if not, then filling in the tip of the lumen on the display.
