Angiography Essays

Forensic imaging, particularly MRI technology is crucial in determining the cause of death in forensic pathology. There are a few main techniques for forensic imaging, magnetic resonance imaging (MRI), post-mortem computed tomography (PMCT), and conventional radiography. The PMCT is generally used for gunshot wounds, detection of gas embolism, trauma cases, and changes in the skeletal system. Some advantages of this technique are that it is fast, easy to handle, good three-dimensional reconstruction

Which imaging modality is the most accurate in vertebral artery dissection diagnosis? Pei Wen Tammy Kwa, Sarah Moore, Paul Ryan, Kate Somers Introduction An arterial dissection is said to occur when the structural integrity of an arterial wall is compromised, permitting blood to collect between layers of the vessel wall to form an intramural haematoma. Arterial dissection is a common cause of stroke in the young, although it may occur at any age. Vertebral artery dissection (VAD) most often occurs

Hyperacusis is found to be associated with both peripheral and central factors. Hyperacusis is often accompanied by a cochlear hearing loss, and this usually involves damage to cochlear hair cells and subsequent auditory nerve degeneration. However, annoyance, fear, and pain hyperacusis must involve central mechanisms. Hyperacusis is a co morbid condition of various other medical conditions that are either peripheral or central factors. Hyperacusis is found in Bell’s palsy, Ménière’s disease, perilymph

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. CT angiography or MR angiography may be performed without threading catheters into the

and confluent in honeycomb appearance.5 Patients with ML may occasionally present with choroidal neovascularization (CNV).6 We report the optical coherence tomography angiography (OCT-A) features of ML compared with our observations on fundus examination, autofluorescence, fluorescein angiography (FA) and indocyanine green angiography (ICGA) in XX eyes. METHODS Ten eyes of five consecutive patients affected with ML (xx females, xx male) were prospectively included. They presented to Ophthalmology

Dense hemorrhage in the retina can cause marked hypofluorescence. In such cases of dense hemorrhage, indocyanine green angiography may be useful because its absorption and emission peak in the near-infrared range allow the light to penetrate the hemorrhage to a greater extent than fluorescein angiography.9 A small case series using indocyanine green angiography has demonstrated these lesions to be pulsatile and contiguous with the arterial wall, pathognomonic of an isolated retinal artery

nonspecific inflammatory disease that causes aortoarterial stenoses/occlusion or dilatation • The disease, which is rare in North America, has a higher prevalence among Asian populations and affects mostly young women • MRI and CT angiography have replaced conventional angiography as the diagnostic tests of choice • Treatment typically starts with inflammation reduction with corticosteroids, with other immunosuppressants added if there is evidence of progression of vascular disease, re-elevation of inflammatory

• What will be your differential diagnoses for this patient? My differential diagnosis for this child would be: 1. Kawasaki disease. 2. Infectious disease such as rubeola, streptococcal scarlet fever, Lyme disease, Rocky mountain spotted fever, infectious mononucleosis. 3. Drug reaction; Stevens-Johnson syndrome 4. Juvenile rheumatoid arthritis. • What specific physical exam findings support these differential diagnoses? I will quickly assess this child overall appearance for distress, signs of

Macular degeneration is a degenerative disorder of the central part of the retina known as the macula, which is responsible for central vision. Its cause is unknown, although it is known that the patient's age is the main risk factor. The macula is the part of the retina that allows you to read, watch television or recognize faces of people. Today, it is the leading cause of legal blindness in people over sixty years. However, peripheral vision remains unchanged, so that patients can manage without

advised by physician, eating, drinking, exercising and medications may be continued as normal afterwards. Allow the patient to ask questions. If unsure about the answer, it is okay to confirm with the physician. Have the patient sign Fluorescein Angiography Procedure Consent Form. As the physician begins to inject the dye, the patient may feel apprehensive. Advising the patient that they may feel “cold or even slight stinging sensation” at injection site as normal, tends to provide the patient assurance

Intestinal Ischemia Overview- Intestinal infarction (or intestinal ischemia) occurs when the blood vessels that flow bowel contract or become obstructed, reducing blood flow. Ischemia can affect the small intestine or the colon, or both. The reduction in blood flow can cause pain and bowel provide permanent injury. The acute intestinal ischemia, i.e. the sudden interruption of the direct circulation to the intestine, it is an emergency and requires immediate surgery; as chronic, which manifests itself

Angiography is the most commonly used technique to visualize the blood vessels with particular interest in the arteries, veins, and the heart chambers. This is traditionally done by injecting a radio-opaque contrast agent into the blood vessel and imaging using X-ray based techniques such as fluoroscopy. The image of the blood vessel thus obtained is called an angiogram or angiograph. Depending on the type of angiogram, access to the blood vessels is gained most commonly through the femoral artery

nasal cautery. Patient should be admitted in the hospital for nasal cautery. If nasal cautery is not able to stop bleeding, then nasal packing (anterior, posterior, merocel) is suggested. If bleeding is still not controlled, arterial ligation, angiography and embolization may be required. Simultaneous treatment of the underlying cause is carried out. References 1. Epistaxis.

children lacking rational capabilities to make informed decisions by interpreting their data. Most forms of neuroimaging release radiation, which, as Lin, E. (2010) stated, increases risk of cancer attributable to disruptions in the cell cycle, and angiography involves the use of a radioactive ‘dye’ which could cause kidney failure or allergic reactions (Chudler, H., PhD, 2017). Different countries have regulations regarding protection of human data, with subjects having the right to withdraw their data

to find out opportunities to acquire the insight of my passion. I signed up and attended the Cardiac Camp at Unicare Heart Institute & Research Center, where I shadowed cardiac invasive procedures: The Coronary, Carotid, Renal, and peripheral Angiographies, Angioplasty, stenting, and implantation of a cardiac pacemaker. It is the motivation which morally supported to organize a free medical camp in India right after completion of my cardiac

increased risk of atherosclerosis. Since calcium salt build-up adds to the acceleration of atherosclerosis, a calcium CT scan is used to see if calcium is present in the blood vessels. One of the most widely used tests for atherosclerosis is a cardiac angiography. This is done by doing a catheterization procedure and utilizing x-rays to look at the blood vessels as a liquid dye is injected into the blood vessels. This can determine where the blockage is and if the treatment should be a CABG surgery or a

A Transient Ischemic Attack, also known as a mini stroke, is an acute illness where blood flow to a certain part of the brain gets blocked which most of the time is caused by a blood clot (Webmd n.d.). After a couple minutes the clot dissolves, blood flow continues again and symptoms disappear. It is called a mini stroke because all the signs and symptoms are the same as a stroke, but the symptoms last a shorter period of time and there is no permanent damage done to the cells. According to the website

Study design and study population: It was a prospective, single arm, open label study that included 99 cases admitted to the catheterization laboratory in Wadi El-Neel hospital between September 2012 and September 2014 and diagnosed as having ischemic heart disease with significant coronary artery stenosis necessitating PCI. We included full history, clinical evaluation, Standard 12-leads surface ECG, Echocardiography, ischemia driven non-invasive testing for controversy patients with chest pain
