A post mortem was previously used by neurologist in order for them examine the human brain and its many functions. However, technology increased accessibility to brain imaging techniques, as well as non-invasive ways to examine the brain in more detail (Morton, Sandhu, & Jones, 2016). MRI and PET Scans are the two modern methods of examining the human brain. Magnetic Resonance Imaging or MRI is a modern day technique which uses detailed computer imagery to identify body structures. An MRI image produces a composite three-dimensional image; the resolution detects tiny changes of structures within the body, identifying strokes, tumours, as well as detecting bleeding and possible swelling of the brain (Galotti, 2008).
MRI is used to visualize brain structures such as white matter, grey matter, and ventricles cerebrospinal fluid and to detect abnormalities. The MRI may be the usually used method for brain tumor growth imaging and location finding. It is really a medical imaging technique used to give the internal structure of the human body and offer high quality images. MRI gives a greater distinctive between different tissues of the body. It is used to improve the grade of diagnosis and treatment of brain.
Computerized tomography (CT) scan combines X-ray images taken from many different directions into cross-sectional views of internal organs. CT scans can provide detailed information about the structures within the heart and lungs. 4.3.2 Lab tests. A test using blood from an artery in your wrist can measure oxygen level.
Because hormones and genetic factors can cause gynecomastia, the plastic surgeon may need to refer a patient to an endocrinologist for either (1) blood and urine studies that would show elevated hormone levels or (2) genetic studies that would show the count and other details of the patient’s chromosomes. An abnormal testicular exam will prompt the surgeon to order an ultrasound of the testes. The surgeon may wish to obtain a mammogram to rule out a breast tumor, which, though unlikely, can occur in men especially with asymmetric breast
Figure 4 Lumbar Puncture In the few cases that are not recognized by CT the health care practitioner may consider performing a lumbar puncture to identify blood in the cerebrospinal fluid that runs in the subarachnoid space. Angiography If the CT or the LP reveals the presence of blood angiography is performed to identify where the aneurysm is located and to plan treatment. Angiography where a catheter is threaded into the arteries of the brain and dye is injected while pictures are taken can demonstrate the anatomy of the arteries and uncover the presence and location of an aneurysm.
However, this is not the only way different treatments are used in conjunction with one another. By carefully assessing the location, size, and stage of the tumor and analyzing the patient’s medical history, age, symptoms, and a variety of other factors, oncologists will design an efficient treatment plan with the least amount of
Aside from producing detailed images of the body, an MRI can measure the tumor’s size. To help create a clearer picture, a special dye called a contrast medium is given before the scan. It can be injected to the patient’s vein or given as a pill to swallow. MRIs create more detailed pictures than CT scans, which are three-dimensional pictures of the inside of the body with an x-ray machine (ACSO). Unlike most cancers, Brain cancer does not use a staging system to describe there tumor.
The treatments and expected outcomes also vary greatly depending upon tumor types and the location. The types of gliomas are formed from different of glias cells and one most rare subtype is astrocytoma or also called as Angiocentric Glioma. This type of tumor is the lesions that originate in blood vessels. Therefore, the classification and diagnosis of this tumor is very challenging.
There will be tests so that the doctor will be able to know the source of your anemia. Some of these tests are blood chemistry test, reticulocyte count which is a kind of blood test, another blood test to see your iron levels, bone marrow test, and fecal occult blood test. Your doctor may use the outcomes of these tests, along with your physical exam and medical information, to be able to have a knowledge about the cause of your anemia.
