Introduction: Gastro Intestinal Tract (GIT) is an important site for wide variety of lesions which include congenital, inflammatory, neoplastic conditions. The invention of flexible fiber-optic endoscope is a very good achievement towards the diagnostic field. With the use of this facility direct vision of diseased mucosa and biopsy of mucosal lesions, therapeutic induction and photographic visualization of the lesions are made possible. Aim of the study: Aim of this study is to know the…

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…

element in the identification, diagnosing, and treatment of many types of medical conditions” (http://www.healthline.com/health/x-ray#Overview1 ). Over the next century, Roentgen and others who followed his work would introduce new modalities of imaging and also drastically improve the efficiency and safety of these modalities as well. One modality that has significantly improved upon the two-dimensional x-ray is known as Computed Tomography. This modality gets its name from the idea of…

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, lung and pancreatic cancers. Magnetic Resonance Imaging (MRI) is…

medical profession. Along with other forms of medical imaging, radiology has changed how diseases can be measured, managed, diagnosed, and treated. The various modalities of radiology provide for clearer and more efficient results, less invasiveness and quicker recovery times, and less costly ways to diagnose and treat patients. Each modality of radiology has different imaging capabilities, which provides for clearer and more efficient results. Imaging modalities have varying complexities that…

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 body. The fact is face is a symmetrical structure, so abnormalities on one side of the face or skull have a mirror…

1.Please explain how medical magnetic resonance imaging (MRI) exploits the magnetic properties of the nucleus. MRI exploits the process known as nuclear magnetic resonance (NMR). In fact the technique used to be called simply NMR or NMR imaging, but the “nuclear” was dropped because of the connotation of radiation hazards from unstable nuclear sources, although there is no logical rationale for such fear. In NMR, a sample of material is placed in a strong magnetic field. The nuclei in the sample…

Neuroimaging is a technique that produce images of brain without any direct contact with the inside of the body such as internal surgery, incision of the skin. Neuroimaging technology become a powerful tool for both research and medical diagnosis. Because these technologies enable noninvasive visualization of the structure and functional segments of the brain. The field of neuroimaging has advanced rapidly day by day due to the development in technology and computational methods. The…

Numerous studies have been conducted on MRI being a useful tool in prenatal imaging of the posterior fossa. Gurbaud (2004) suggests that MRI is useful as a complementary investigation to US in three particular situations. Ranchod, Androniko, & Modi, (2012) detail 4 case studies where MRI was used to diagnose specific posterior fossa abnormalities after having an US. This paper examines research done to examine the posterior fossa in prenatal brains with the use of US and fetal MRI. Literature…
