Digital subtraction angiography (DSA) is a fluoroscopy technique used in interventional radiology to clearly visualize blood vessels in a bony or dense soft tissue environment. Images are produced using contrast medium by subtracting a "pre-contrast image" or mask from subsequent images, once the contrast medium has been introduced into a ...
After the treatment, patients follow up with their physician for several months. The treatment team also orders additional imaging scans to evaluate whether the microwave ablation successfully destroyed the tumor. Plasma-mediated radiofrequency ablation ("coblation") Radiofrequency ablation is a treatment that uses heat to destroy multiple ...
Fluorescence guided surgery (FGS), also called fluorescence image-guided surgery, or in the specific case of tumor resection, fluorescence guided resection, is a medical imaging technique used to detect fluorescently labelled structures during surgery. [1]
Two forms of radiographic images are in use in medical imaging. Projection radiography and fluoroscopy, with the latter being useful for catheter guidance. These 2D techniques are still in wide use despite the advance of 3D tomography due to the low cost, high resolution, and depending on the application, lower radiation dosages with 2D technique.
The problem of radiation injuries due to fluoroscopy has been further addressed in review articles in 2000 [61] and 2010. [62] While deterministic radiation effects are a possibility, radiation burns are not typical in standard fluoroscopic procedures. Most procedures sufficiently long in duration to produce radiation burns are part of ...
The treatment plan can then be designed with a knowledge of the full range of possible positions of important organs, and the tumour (target) itself. [ 8 ] 4DCT will usually involve a gating technique, such as breathing tracking, so that image acquisition is automatically triggered at set points. [ 9 ]
Aortography involves placement of a catheter in the aorta and injection of contrast material while taking X-rays of the aorta.The procedure is known as an aortogram. The diagnosis of aortic dissection can be made by visualization of the intimal flap and flow of contrast material in both the true lumen and the false lumen.
