Tumors of the pituitary gland are mostly benign adenomas that remain within the pituitary gland and do no metastasize, but cause symptoms due to hormone production (if they cause hormone production) and the mass effect of the tumor. Most pituitary gland tumors may not require treatment, but if the tumor is compressing the optic nerve, then surgery is necessary. There are two main surgical approaches: an endoscopic trans-nasal trans-sphenoidal (ETNTS) method and a trans-cranial
However, wall abnormalities in some sections of the VA are seldom depicted on ultrasound. Furthermore, although ultrasound can successfully identify stenosis in certain areas of the VA, it cannot differentiate between stenosis due to a VAD and stenosis due to atherosclerotic
As weird as it may sound, some technologies are actually being inserted into patient's’ bodies and performing operations on their own. This idea may sound extremely radical and invasive; however, these technologies take less time and are less likely to penetrate organs and other structures. A technology like this, known as the cyberknife, can reach a tumor without destroying tissue, organs or any other body parts surrounding it and opens the door for a new type of surgery called radiosurgery (Gardner). Radiosurgery, as a result of the development of surgical technology, is a minimally invasive approach which allows a surgeon to cut open a small portion of a tumour and eliminate part of the tumour through gamma radiation. This reveals that technology in surgery allows for new operations to be created from medical innovation.
Introduction: There are many abnormalities that may affect the brain such as, seizures, tumors and stroke. To evaluate this type of diseases, we need special procedures like MRI and CT. In this report I’m going to talk about MRI and the special techniques that used in the case of stroke. Magnetic resonance imaging is non-invasive procedure that provides anatomical and functional information. MRI provides cross-sectional images with an ability to reconstruct data to other plains.
Obstetric anesthesia is a challenge in these patients because of complex spinal defects and could make regional anesthesia difficult but not absolutely contraindicated. A spina bifida cystica patient with a lesion above T11 is unlikely to experience labor pain. However there is a potential risk of autonomic hyper reflexia in patients with thoracic lesions (T5–T8) and prophylaxis should be provided. There is an increased risk of accidental dural puncture as well as failed block and excessive cranial spread of the local anesthetic while performing epidural blockade. In most cases the obstetric anaesthetist also faces the challenge of dealing with surgically scarred backs.
Abstract— Radiologists have only the 2D mammographic reports to detect the abnormalities present, which do not give the feel that how the abnormalities exactly look like. Hence there is a need of representing the abnormalities (like mass, tumor, micro calcification) in 3D to increase the accuracy in detection. A literature survey is done about the various techniques used in segmentation and 3D representation of the abnormalities. Keywords—mammography, 2D, 3D representation, segmentation. I.
A CT scan, CT standing for computed tomography, uses X-Rays from many different angels to make a detailed picture of the structures inside the body. It allows doctors to see what is happening inside the body without having to cut somebody open. A CT scan is taken in a donut shaped ring and a bed, the bed gets rolled into the scanner. An MRI, standing for magnetic resonance imagining, use strong magnetic fields to make photos of the organs in a person's body without cutting the body open. An MRI machine does not use X-rays to make photos.
Pap smears are not conducted at KHMH; however, they are assessed by the specialists. The colposcopy equipment at KHMH enables the observation and study of living tissue within the cervix and vaginal areas. • Orthopedics- Orthopedics is the medical specialty focusing on the diagnosis, treatment, and repair of bones, muscles, ligaments, tendons, and joints. This includes broken bones, torn ligaments, and some spinal injuries. • Paediatrics- Paediatric service KHMH has three specialists attached to the unit.
Unlike conventional X-ray, CT, MRI and ultrasound operate without ionizing radiation. MRI uses strong magnetic fields, which produce no known irreversible biological effects in humans. Diagnostic ultrasound systems use high-frequency sound waves to produce images of soft tissue and internal body organs. III. DIFFERENT TYPES OF MEDICAL IMAGES There are several methods of medical imaging – each uses different technology to create a different type of image.
It produces a computerized image from the use of magnetic fields. It creates a picture of the activity in the are being scanned. Without the use of computers, doctors would need to preform invasive surgery in order to find physical and operational defects within the body as a form of diagnosis (Conyers, para 2). Medical research has also advanced with the use of computers. Doctors and scientists have a way to collect all data and information and share it in large databases.
