Detection Of Brain Tumor Detection Essay

A person has a 0.55–0.7% chance of developing any type of brain tumor in their lifetime (Mohammadi and Schroeder 1). A brain tumor is a mass of abnormal cells located somewhere in the brain. Brain tumors can be caused by many different disorders including Tuberous Sclerosis Complex (TSC). Some tumors caused by this disorder are inoperable. Inoperable brain tumors can now be treated using new advanced technology. Technological advances provide new hope for patients who have inoperable brain tumors and TSC.

Once a person has been diagnosed with brain cancer, treatment should begin immediately. Treatment for brain tumors involves any combination of surgery, radiation, and chemotherapy. Some tumors require several different surgical procedures; some can be treated with radiation alone. Surgery is the best process to remove a brain tumor. Surgery attempts to remove most, if not all of the tumor. Once most of the tumor is removed, the rest of the tumor can be removed through a process called radiotherapy.

There are over 12,000 cases diagnosed each year.Once an MRI is taken and the mass is seen, this can only be diagnosed definitively once surgery has taken place and they have taken a sample and put it under a microscope to determine grade. The single hardest part to remove while in surgery is known as the feelers, they are thin like tentacles that grow out from the tumor and imbed themselves into the surrounding brain tissue. It is mostly defined in the brain area and rarely goes anywhere else in the body. the highest grade is four how they make that determination is taking the sample, while looking under a microscope to see how it

The primary ones include these types. Gliomas, the most common brain tumor involving the brain tissue. There are different grades and even types of gliomas. But if the tumor grade is higher, it will probably grow faster. Medullblastomas are brain tumors that in young children. Without treatment it will spread rapidly into the spinal fluid and other parts of the brain. But almost or half of the brain tumors found are benign. These types of brain tumors are usually Meningiomas and Neuromas. Meningiomas begin in the tissue membranes. Neuromas are in the nerves mostly in people over

Tumors can be classified into three types: 1) benign 2) pre malignant 3) malignant tumor. Benign tumors are those which are incapable of abrupt expanding and affecting the other healthy brain tissues. Premalignant tumor is a pre cancerous stage, if not treated properly it may lead to cancers. It is often considered as a disease. Malignant tumor grows rapidly with time an ultimately leads to death of patient. Malignant is a medical term describing a sever growth of a disease. The most common primary brain Tumors are gliomas, wherein 70% are in the group of malignant gliomas, glioblastoma multiform (GBM).The GBM is one of the highest malignant human

Glioma is a tumor that is a type of brain cancer. Glioma tumors are made up by cells called glial cells. Glial cells normally provide nutrition, oxygen, and structural support to the brain. Three types of glial cells can produce tumors. Gliomas are named after the type of glial cell that is involved in the tumor. A tumor is formed when the glial cells grow into an abnormal mass of tissue. Gliomas are one of the most common types of brain tumors that occur in adults.

The next step is to do tests on the brain itself to rule out other possible conditions. Doctors will often do a CT scan first, then an MRI, and possibly a PET scan; these tests will show abnormalities of the brain, and they will help rule out tumors, clots, or if the patient has had a stroke.

Combination of calculated ADC values from tumoral core and specific metabolite ratios obtained by MR spectroscopy add more information to MR imaging in the differentiation and grading of brain tumors and more useful together than each alone. Magnetic resonance spectroscopy imaging has superior diagnostic performance in diagnosis of glioma grades compared with diffusion weighted imaging (DWI)

A brain tumor is a mass or development of irregular cells in your cerebrum or near your mind. There are different types of brain tumor exist which even are health hazardous. Essential brain tumors rise up out of the different cells that make up the cerebrum and focal sensory system and are named for the sort of cell in which they first shape. Gliomas and astrocytic tumors are the most common types of adult brain

Magnetic resonance imaging (MRI) one of the primary imaging modalities used to evaluate and diagnose chordoma. While MRI is done in conjunction with other modalities like computed tomography (CT) to obtain data, studies have shown that there are advantages to MRI not seen in CT. One of them is using diffusion-weighted MRI to assess and differentiate chordoma from other cranial tumors that have “overlapping presentations and anatomic imaging features” such as chondrosarcoma (Yeom et al, 1056). Diffusion-weighted MRI uses the motion of particles in fluid within voxels to measure cellular density and the nuclear-to-cytoplasmic ratio. In a study, Dr. Kristen Yeom and colleagues examined patients with the following parameters: “TR/TE, 8300/70 ms at 1.5T and 10,000/80 ms at 3T, b=1000 s/mm2, three directions, 4 to 5 mm thickness, 0 skip” (Yeom et al, 1059). They looked at the data for Apparent Diffusion Coefficient (ADC), which differed for the types of tumors; low ADC signifies abnormal diffusion restriction. The results yielded that classic chordoma had lower ADC values averaging 1460x10-6 mm2/s than chondrosarcoma’s 1977x10-6 mm2/s. Although researchers would be unlikely to distinguish chordoma and chondrosarcoma “on the basis of signal intensity characteristics” of T1 and T2 images, there are still uses for them (Oot el al, 568).

Neuroblastoma is a type of cancer. Cancer is when cells grow out of control, join together, and form a tumor. Neuroblastoma tumors start in cells in the nerves. The cancer can then spread to other parts of the body. Most often, tumors are found in the abdomen, the glands that make hormones, and on top of the kidneys (adrenal glands).

Common malignant brain cancers increase significantly according to statistical data collected by the National Cancer Institute. In 1984, the annual incidence rates of primary brain tumor and primary brain lymphoma also increased notably, the rate of lymphoma almost tripling,

Tumors are one of the most feared diseases of our time. Many people upon hearing the word “tumor” immediately resonate to the conclusion of it being cancer, which is not necessarily true. Tumors fall into to two main types, benign and malignant. Although they are considerably different in tissue invasion, their nature that makes them distinct and symptoms, they are also quite similar in the way they recur in the same location, growth size and their health risks.

During the early 1970’s something called Computed Tomography (CT) Scanning was introduced into medicine. The CT scans were able to provide the first clear image of the brain and brain tumors. This was done by using X-Rays which provided doctors with images of a section or “slice” of the brain. In the following decades, CT Scanning becomes more and more refined and is now also being paired with other imaging techniques such as Magnetic Resonance Imaging (MRI) which was invented by Damadian in 1977 (Filler, 2009).

Neurologically, trauma to the brain can be seen as bleeding or swelling. Other abnormalities often found include: brain aneurysms, stroke, tumors of the brain, as well as inflammation of the spine. In addition, Neurosurgeons use an MRI scan not only for analyzing the brain anatomy but also in evaluating the structure of the spinal cord after trauma. It is also used when considering problems associated with the vertebrae or intervertebral discs in the spine. Finally, an MRI scan can also evaluate the structure of the heart and aorta, to detect aneurysms or tears.
