Stereotactic biopsy to detect any type of brain tumor seems feasible. In determining any point within the cranial cavity of the basic principles of mathematics are used. In fact, using three coordinate points. In this way, by means of needle biopsy guided stereotactic and application of the three coordinates of the point already in radiologic images such as CT and MRI were done. Then, using the small size of samples
A brain tumor, “is an abnormal, excessive growth of tissue in the brain...Primary brain tumors are classified as either benign or malignant” (“Brain Tumor”). There are over 130 different types of tumors and each one is classified by the type of cell that they develop from. One specific type of tumor is a meningioma. The specific origins of this type of tumor are unspecified, but have been associated with radiation or some type of genetic alteration. The meningioma, has distinctive methods of diagnosis, manifestations with a variety of symptoms, diverse treatment options and prognosis is based on a multitude of factors.
This may also require an injection of dye. CT scans have virtually replaced pyelogram and ultrasound as a tool for diagnosing kidney cancer. • Magnetic resonance imaging (MRI) uses strong magnets and radio waves to create detailed images of soft tissues in your body. You may need an injection of a contrast agent to create better pictures. • Renal arteriogram: This test is used to evaluate the blood supply to the tumor.
Core needle biopsy (CNB) can yield the tissues for fibrotic and hypocellular lesions from which the FNAC is often inadequate. It provides details of the tissue architecture and gives more material for adjuvant studies. Though, CNB is more traumatic, and have high risk of complications, requiring local anesthesia and strict sterilization procedures.
Some of the many uses include: • detection of foreign objects - such as swallowed toys, bullet fragements and kitchen untensils • as a surgical tool – assist doctors to accurately perform surgeries. For example, X-ray images may be taken during an orthopaedic surgery to let the surgeon see if the implanted device (e.g artifical leg) is in position, or if the fracture is aligned. • diagnosis of dislocations and fractures – x-ray examinations can detect broken bones and reveal if the bones of a joint are irregularly positioned • diagnosis of bone or joint conditions – e.g arthritis, scoliosis, osteoporosis and bone cancer • diagnosis of mouth conditions – e.g reveal areas of decay that may not be visible with an oral examination or bone loss that accompanies gum disease • diagnosis of conditions in the thoracic cavity– such as lung cancer, pneumonia, heart failure or
Serologic testing is most simple and helpful. B henselae is difficult to culture. In selected cases, excision of an involved node is useful for histopathologic examination. Fine-needle aspira- tion biopsy is less invasive and may be preferred if feasible. Conventional stains can demonstrate granulomas and stellate necrosis, and silver stains can detect suggestive bacillary forms.
Radical Prostatectomy is the main type of surgery for prostate cancer. Doing so, the surgeon removes the entire prostate gland and some of the tissue around it. To do the prostatectomy, the surgeon operates through a single long incision to remove the prostate and nearby tissues (American Cancer Society). The skin incision will go through your lower abdomen, from the belly button down to the pubic bone. The nerves may be removed as well if the cancer is growing in or close to them.
Thereafter, various types of biopsy tests are carried out on the cells for further verification. These tests are done by cutting a small portion of body cells or tissue. A pathologist (specialized in examining body cells) analyzes the removed portion under a microscope. In some cases, the doctor needs the help of an ultrasound or CT scan to direct the biopsy needle to cut the correct portion of tissue. For some patients, a number of biopsies are needed to get clarification on the tumor.
The term “arthroscopy” basically means “to look inside the joint”. (Dictionary) Surgeons have been performing this surgery since the 1970’s. During surgery, the arthroscope, i.e. a small camera is placed into the shoulder joint. A television screen is then used to display pictures from the camera for the surgeon to see and he/she uses these images to guide small surgical instruments.
The most usual use of x-rays is checking for broken bones, it can check for breast cancer. There are benefit and risks of X-ray examination. • No radiation is in a patient's body after an x-ray • Bone x-rays are the easiest way for a doctor to view bone injuries and fractures • X-ray equipment is not inexpensive and available in emergency rooms. • Convenient for both patients and doctors • X-ray imaging is easy; it is particularly useful in emergency treatment. Risks • There is always a chance of cancer from too much radiation.
