Summary
The basic problem in this disorder is abnormal hyperfunction of the thyroid gland leading to excessive or larger than normal secretion of thyroid hormones, namely T3 and T4. Since the basic content of these hormones is iodine, thyroid gland…

Download file to see previous pages In clinical practice different hyperthyroid conditions such as Graves’ disease, hyperthyroid goiter, and other conditions such as toxic multinodular or nodular goitre need assessment of activity of the gland. In this review, contemporary literature has been reviewed to update current knowledge on this topic. This assignment reveals that radionuclide imaging is an important diagnostic modality in the workup of hyperthyroid disorders, but despite that, in some cases the diagnostic yield is better with ultrasonography or PET scanning. In some cases, combined use of these imaging investigations pinpoints the diagnosis in a more suitable manner. Review of these articles and the knowledge apparent may be used to frame a guideline of advice regarding imaging practice in this area.
The thyroid gland produces two hormones, namely, thyroxin (T4) and triiodothyronine (T3). These are known to play important physiological roles in the human body. Anatomically, the thyroid gland is located in the neck, in front of the trachea. It comprises of two lobes, right and left, connected by a narrow bridge of thyroid tissue, known as isthmus. It is a very highly vascular organ. The normal adult thyroid gland consists of follicles lined by thyroid follicular cells that contain large amount of thyroglobulin. This serves as the protein precursor of the thyroid hormones (Broome, 2006). Endocrinologically, increased need for thyroid hormone leads to a signal pathway mediated by thyroid stimulating hormone (TSH) leading to release of active hormone from a bound state with thyroglobulin to a free state, eventually being secreted into the blood stream. When there is hypersecretion of thyroid hormones due to any cause, the condition is known as hyperthyroidism. Usually hyperthyroidism is indicated by an elevated level of TSH. Therefore, in clinical practice the diagnosis of hyperthyroidism is made by finding an abnormally elevated TSH level which ...Download file to see next pagesRead More

...?Nuclear Medicine Nuclear medicine is a branch of medicine in which negligent amount of radioactive material is used to treat or diagnose various diseases. The diseases which mainly can be diagnosed or cured with nuclear medicine are cancer, heart disease or other abnormalities of body. In nuclear medicine, technique imaging procedure is used to diagnose or treat disease. The imaging procedure in this medicinal field is non – invasive and is comprised of painless medical tests. The imaging scans involved in nuclear medicine make use of radioactive material like radiotracers and radiopharmaceuticals. Depending on the nature of treatment the radioactive material is injected, inhaled or swallowed to produce energy called gamma rays... in the...

..., and does not give the exact high resolution images needed for visualisation of stones (Bushberg et al., 2002, p. 363). MRI can also be used however, it takes a longer time to produce clear images, which takes tens of minutes, and the patient must be rather still within this time frame (ibid., p. 10). Other diagnostic tests which utilise nuclear medicine such as PET and ERCP, if ever available, could still pose harm to the foetus because aside from using radioactive isotopes for visualisation, these also use high-energy beams for detection, which could again cause irreparable damage to regions of active cell division in a foetus. Therefore, the safest...

...breasts. According to Edelman (1996, p.48), acoustic impedance is calculated as density of the tissues (p) X velocity of the ultrasound propagation (v). Hence Z=pv and is measured in kgm-2s-1. The basis of examination of different tissues in ultrasound is the use of echoes. For example bones or calcified tumors tend to have the highest acoustic impedance as compared to the soft tissues such as fats, fibroids and glandular tissues. On the other hand, refraction of the waves may take place at the oblique angles found between the different tissues of the body and this often results in errors of their depth estimation. Ultrasound imaging technique is preferred as one of the modalities which...

...diseases in the gastrointestinal tract, studies show that 18F DOPA PET is highly sensitive and specific for detection of pheochromocytomas and has potential as the functional imaging method of the future (Radiological Society of South America, 2002). And recently, researchers have been looking into the possibility of using Positron emission tomography (PET) and other nuclear medicine modalities in staging gastrointestinal cancer (Wiley InterScience, 2001). Summary Nuclear Medicine is actually under Radiology and is a very promising procedure in determining internal diseases. This diagnosis uses radiopharmaceutical...

Note the wide disparity of lesion extent with the two stress techniques. In patients unable to perform a maximal exercise test dipyridamole imaging demonstrated more extensive disease than exercise studies. However lesions were more extensive on exercise studies in patients who were able to perform a maximal exercise test. (Klaus, 2008, 61) 3.

...NUCLEAR MEDICINE Radiation exploited in most nuclear medicine procedures Gamma radiations have been long been used in nuclear medicine. The use has been both therapeutic and diagnostic. The procedure has a technical aspect and the scientific aspect in which it become useful. The technical aspect involves injection of a radioactive tracer inside the body and then it is directed to a place where there is an abnormality or pathology. Once the tracer get to the place of pathology, the technical part will have achieved its goal (Hada, 2014).Most of the radioactive tracers are introduced by injection while other through...
