In medical imaging, artifacts are misrepresentations of tissue structures produced by imaging techniques such as ultrasound, X-ray, CT scan, and magnetic resonance imaging (MRI).
Endomicroscopy is a technique for obtaining histology-like images from inside the human body in real-time, [1] [2] [3] a process known as ‘optical biopsy’. [ 4 ] [ 5 ] It generally refers to fluorescence confocal microscopy , although multi-photon microscopy and optical coherence tomography have also been adapted for endoscopic use.
Confocal endoscopy, or confocal laser endomicroscopy (CLE), is a modern imaging technique that allows the examination of real-time microscopic and histological features inside the body. In the word "endomicroscopy", endo- means "within" and -skopein means "to view or observe".
Unlike many other medical imaging techniques, endoscopes are inserted directly into the organ. There are many types of endoscopies. Depending on the site in the body and type of procedure, an endoscopy may be performed by either a doctor or a surgeon. A patient may be fully conscious or anaesthetised during the procedure.
MIP Display was invented for use in Nuclear Medicine by Jerold Wallis, MD, in 1988 at Washington University in St. Louis, and subsequently published in IEEE Transactions on Medical Imaging. [2] In the setting of Nuclear Medicine, it was originally called MAP (Maximum Activity Projection). [3] [4]
ConeBeam computerized tomography image of a post-operative orthognathic surgery. Oral and maxillofacial radiology, also known as dental and maxillofacial radiology, or even more common DentoMaxilloFacial Radiology, is the specialty of dentistry concerned with performance and interpretation of diagnostic imaging used for examining the craniofacial, dental and adjacent structures.
In medical or research imaging, an incidental imaging finding (also called an incidentaloma) is an unanticipated finding which is not related to the original diagnostic inquiry. As with other types of incidental medical findings , they may represent a diagnostic, ethical, and philosophical dilemma because their significance is unclear.
The basic principle of ghosting can be explained with the help of Echo-Planar Imaging (EPI). Echo-planar imaging is an MRI technique that reduces the time of data acquisition to reduce capture of patient movement. An image in the EPI can be captured in between 20-100 milliseconds.
