For the majority of patients receive an MRI it is safe. The MRI uses magnetic fields and radio frequencies to create images; therefore, there is no need to use harmful ionizing radiation. Patients are asked to arrive 20 minutes prior to the procedure to complete paperwork. Before the exam, an MRI technologist must find out some information about the participant's medical history, and his/her status in order to evaluate the patient safety risk. For example, knowing if the patient might be pregnant is very critical, but in some cases, MRI could be performed safely late in a pregnancy the doctor needs to check the woman’s abdominal area or her baby. Some medical devices are not be safe to be used with an MRI, such as a cardiac pacemaker, a specific type of vascular stent, and inner ear implants (Robinson, 2012). Furthermore, metal objects within the body can also cause problems with the MRI. For example, objects such as watches, jewelry, pants, and eyeglasses are not allowed during the exam because they can be damaged or put the patient in danger. It is also advisable for the patient to take out any removable prostheses, such as bridges, before the scan and leave them outside the MRI room. Typically, however, implants are made from titanium and are not magnetic, so those are safe during the scan. With full dental braces, examiners may prefer not to scan patients because of image distortion. Moreover, the strong magnetic fields created during an MRI scan can damage to heart pacemakers. However, other implants seem to work fine during the MRI. In general, a patient needs to wear either a hospital gown or clothing without metal pieces, such as zippers because it might give a blurry image (Abdominal MRI scan, 2012). Although an abdomi... ... middle of paper ... ...he patient because of her age and condition. Also, lung tissue does show up well using MRI (O’Loughlin, 2014). In this patient’s case, a CT scan with different windows can be used to visualize the lung structure. However, MRI can show vascular structure very well, which is useful since she may have a problem in her cardiovascular system. Thus, MRI is recommended for this patient. In conclusion, this report evaluates a MRI for the 64-year-old woman who has been suffering from abdominal cramps and chronic diarrhea with the goal of obtaining a diagnosis. Although the MRI has few limitations, it does have several benefits that help the examination to make the correct diagnosis for different systems. This will allow the physician the ability to give the patients the correct treatment. Thus, choosing and understand the images will play an important role in treatment.
HPI: MR is a 70 y.o. male patient who presents to ER with constant, dull and RUQ abdominal pain onset yesterday that irradiate to the back of right shoulder. Client also c/o nauseas, vomiting and black stool x2 this morning. He reports that currently resides in an ALF; they called the ambulance after his second episodes of black stool. Pt reports he drank Pepto-Bismol yesterday evening without relief. Pt states that he never experienced similar symptoms in the past. Denies any CP, emesis, hematochezia or any other associated symptoms at this time. Client was found with past history gallbladder problems years ago.
Next, we will discuss the problems identified in the case study. The first problem is design deficiency especially in the MRI room and on the oxygen tank. As explained previously, there is poor communication in the MRI room due to the absence of microphone to inform the technologist in the console room about the existing problem. The oxygen tank meanwhile did not have a proper indication panel that informs the state of the oxygen level in the tank. Design deficiency is a major problem because in a state of inadequacy, needed materials for the safety and optimal environment cannot be
My interest in MRI started when I first read the book “MRI, The Basics” written by the author Ray Hashemi. By the time I successfully finished my MRI clinical placement in Tehran University of Medical Sciences, I knew for sure that MRI would be the field I would be choosing to take on. What attracts me most about MRI is how beautifully scientist could create a technology that can take advantage of the magnetic moments of human body for imaging it without any harms of ionizing radiation. Although there are drawbacks to MRI, combining it with other modalities would be a more effective approach to an accurate diagnosis.
In the radiology profession first you must write the patient’s file. This includes information about insurance, medical history, what the required x-ray is for and where it is going to be taken on the body. Writing in this way is similar to writing a small research paper. You must do research on the patients and there history and what insurance they have. Writing the report is important because the information must be accurate so the patient can be helped as much as possible. If the information about medical history is incorrect it can cause a huge problem for the patient. For example, if the patient is claustrophobic they would need to get an open room x-ray where the patient isn’t in an enclosed tube so they don’t have a panic attack and potentially injure themselves and others. It is very important to make sure the report has the correct area of where the x-ray needs to be taken. Having the wrong part of the body x-...
The MRI, on the other hand is less expensive and much safer (as it doesn’t expose the patient to potentially harmful radioactive chemicals). The MRI or magnetic resonance imaging device, as an safer alternative, applies a powerful magnetic field around the head of the patient.
Although lung cancer is generally operable, by using either traditional open surgery, or one of the less intrusive and more sophisticated video-assisted thoracoscopic surgeries (VATS), often it may not be considered to be the best option for a patient. Where ill-health is a factor, or either the size and location of the tumor is deemed to be a consideration, other forms of treatment may well have to be considered.
IBS is a functional GI disorder, meaning it cannot be explained by any specific structural or biochemical abnormality. The disorder is subdivided into three different types, which are named on the basis of the predominant symptom – IBS-D (diarrhea-predominant), IBS-C (constipation-predominant), IBS-M (mixed diarrhea and constipation). Clinical presentation varies considerably with regard to the quality of the predominant feature and the overall severity of symptoms. Formal diagnosis is based on the most recent Rome III criteria, which require that a patient experience recurrent abdominal discomfort of at least 3 days per month over the previous 3 months, with a total symptom duration of at least 6 months, in...

...s operated by a magnet there will be a lot of artifact because of the metal being inside the patient. There has also been a discovery of the contrast used in certain MRI exams can cause severe kidney damage. This is a rare effect and only happens to about five percent of patients that receive an MRI ("About mri scans," 2014).
As a starting point in CT diagnostic imaging the form of radiation used to provide an image are x-rays photons , this can also be called an external radiation dose which detect a pathological condition of an organ or tissue and therefore it is more organ specific. However the physics process can be described as the radiation passes through the body it is received by a detector and then integrated by a computer to obtain a cross-sectional image (axial). In this case the ability of a CT scanner is to create only axial two dimensional images using a mathematical algorithm for image reconstruction. In contrast in RNI the main property for producing a diagnostic image involves the administration of small amounts of radiotracers or usually called radiopharmaceutical drugs to the patient by injection or oral. Radio meaning the emitted of gamma rays and pharmaceutical represents the compound to which a nuclide is bounded or attached. Unlike CT has the ability to give information about the physiological function of a body system. The radiopharmaceutical often referred to as a nuclide has the ability to emit ga...
Many of the experts agree that the dose should be kept as low as possible with minimal exposure to the fetus of any age. It has been shown that fetuses before 16 weeks are the most sensitive to any dose of ionizing radiation and have been shown to have lower IQ’s and verbal scores than those exposed after 16 weeks. Fetuses exposed after 16 weeks have the same amount of risk as children up to 10 years old getting cancer. It is very important to take in to consideration gestational age, shielding, the position of the x-ray tube and the amount of necessity that is considered in taking a radiographic image or performing a radiographic procedure in a pregnant woman.

...why does the technologist step behind a shield to prevent exposure to themself?" The radiation dose for each exam is relatively small, but over time, the dose can add up. There are many state and federal regulations limiting the total radiation dose that may be received by people working with radiation. To comply with those regulations, the technologist must follow strict precautions to keep their cumulative exposure to a minimum.
This was his second episode since 10 days ago where he develop the same pain at his right flank. He suddenly experienced severe pain 8 hours before admission when the pain shifts to his right lower quadrant of his abdomen. The onset is at 6.30 am before worsening at 10 p.m to 2 p.m. He described the pain as continuous sharp pain and gradually increased in severity. There is no radiation of the pain. The pain was exaggerated on movement and touch. There were no relieving factor and he scale the severity as 7/10. He experienced fever for 1 day prior to admission. It was a mild grade continuous fever. He does not experienced chills and rigor. The patient does not experience any nausea or vomiting, no dysphagia, no pain during micturition and no alteration in bowel habit. He experienced loss of appetite but not notice any weight loss.
MRI has become the modality of choice when imaging soft tissue densities and recently, MRI breast scans have become an accessory exam to regular screening mammography. Breast MRI’s are becoming a standard for women with especially high risks of developing breast cancer due to MRI’s ability to superbly image soft tissues with high contrast. Breast MRI’s have several advantages over traditional mammography. Breast MRI’s are more likely to catch abnormal cells in the breast as the scans are usually performed with image enhancing contrast agents which highlights areas of interest (Newstead, 2012). MRI also does not utilize ionizing radiation to produce images which is a great advantage for some patients. Another advantage of breast MRI is superior
