Tracking Subtraction Perspective

Trace subtraction fluoroscopy (TSF) is a landmark technique that directs the catheter into the target vessel quickly and accurately. It is mainly used for the diagnosis and interventional treatment of pelvic tumors, pelvic vascular diseases, pelvic hemorrhage and ectopic pregnancy. Abnormal shadows were found on the fluoroscopic images, which may have pelvic tumors, pelvic vascular disease, intra-pelvic hemorrhage, and ectopic pregnancy. Basic Information Specialist classification: Oncology examination classification: X-ray Applicable gender: whether men and women apply fasting: not fasting Tips: Check your relaxation, face it positively, and actively cooperate with the inspection. Normal value There are no special contraindications before the check. During the examination, it is required to check the feeling of relaxation and listen to the doctor's instructions. Clinical significance Abnormal results: abnormal shadows were found on the fluoroscopy results image, which may have pelvic tumors, pelvic vascular disease, intra-pelvic hemorrhage, and ectopic pregnancy. People who need to be examined: middle-aged women. Precautions Check for abnormal lumps and areas. Inspection process In contrast, the contrast agent is injected first, and when the blood vessel is best developed, the frozen frozen image is stopped (some machines are photographed), and the image is used as a mask, and then the intubated image under the perspective is subtracted to form a subtraction blood vessel image. The trajectory marks are superimposed on the fluoroscopic image, and then the normal see-through cannula is performed. In this way, the direction of the catheter and the specific position of the tip can be clearly displayed, guiding the operator to smoothly insert the catheter into the target area. Not suitable for the crowd Pregnant women and people who are allergic to carbon monoxide. Adverse reactions and risks No complications.
