Interventional radiology

ways that X-ray, CT, and MRI alone cannot, providing the most accurate way to study and diagnose specific abnormalities within the body’s elements, making nuclear medicine one of the most valuable modality radiology has to offer. Nuclear medicine brings a unique aspect to the field of radiology. Radiologists use X-ray, MRI, and CT to detect the anatomical aspect of diagnosing conditions,…

Medical image analysis plays a vital role in medical diagnosis is a broad area of education and research attention. Medical imaging techniques become a nature look with different characteristics depend upon the selection of modalities with the requirements ( Li Luo 2007). For example, CT offer supreme information on denser tissue with smaller amount distortion whereas Magnetic Resonance Image (MRI) offer superior information on soft tissue with supplementary distortion (Yong Yang et.al. 2010)…

Computed tomography (CT) is a computerized method that uses a computer to process the data collected from the passage of x-ray beams through the region of interest. The multislice CT (MSCT) means CT that the system equipped with multiple rows of CT detectors to create images of multiple sections. The data obtained from the patient will be transformed into “cuts” or cross-sectional slices of the human body (Romans, 2011). In early 1970, they use a single slice CT scan that contributes too many…

November 8th, 1895 is a day that will forever be considered one of the most significant days in the world of medicine. This is the day that a German Scientist named Wilhelm C. Roentgen accidentally discovered the x-ray while experimenting with a Crookes tube. This discovery allowed the inside of the human body to be viewed without having to perform unnecessary surgery. From this discovery, x-rays became “a key element in the identification, diagnosing, and treatment of many types of medical…

a significant number of images from the same dataset when he interpreted them a second time. The Board of Roentgenology advised that such findings be subjected to a thorough investigation. This, accordingly, led to the investigation of error in radiology and the causes that influence radiological…

Computed Tomography (CT), also commonly referred to as a CAT scan, is a medical imaging method that combines multiple X-ray projections taken from different angles to produce detailed cross-sectional images of areas inside the body. CT images allow doctors to get very precise, 3-D views of certain parts of the body, such as soft tissues, the pelvis, blood vessels, the lungs, the brain, the heart, abdomen and bones. CT is also often the preferred method of diagnosing many cancers, such as liver,…

The term angulation when used in radiology refers to the direction and degree the X-ray tube is moved from its normal “start” position, which is always perpendicular to the to the IR in the Bucky tray. There are many projections that utilize tube angulation for various reasons. Many use it to avoid the superimposition of different anatomic structures. The reason angulation is used is to cause a controlled or expected amount of shape distortion. Shape distortion is altering the normal anatomic…

Cranioplasty is the method of treatment of skull defects; it is required to protect the underlying brain, correct major aesthetic deformities or both (Pompili et al., 1998). Today, three-dimensional (3D) models of anatomical structures can be constructed based on anatomical information from scanning data coming from computerized tomography (CT). Magnetic resonance imaging (MRI) data is used to 3D modelling of soft tissues and computerized tomography (CT) for Hard tissues (i.e. bone) of the human…

Modified Barium Swallow Modified Barium Swallows also simply deemed MBS’s are fluoroscopic procedures used to determine the underlying cause of impaired swallowing (dysphasia). The Modified Barium Swallow study will help determine a treatment option for people who are having difficulty swallowing or aspirating. The procedure is painless and not at all time consuming. The study consists of swallowing different consistencies of a radiopaque agent called Barium and at the conclusion of the exam…

Magnetic resonance imaging uses non-aggressive magnetic imaging technology to produce a three dimensional image of a bodily part. This is similar yet different to the use of x-ray imaging for similar purposes, however, MRI has no trace of the damaging ionizing radiation given off during the use of x-rays and CT scans. MRI is generally used for inspection and detection in the muscles, ligaments and soft tissue through the human body and can be used to monitor treatments, diagnosis of a patient…
