Ct, Mri, And Coronal Images Of The Body Planes - 1477 Words

CT This week I rotated through CT. CT is computed tomography. CT uses special x-ray machines to show detailed images of the body planes. This machine splits the body into axial, sagittal, and coronal images on one scan. Some CT scans are done with contrast and some are done without contrast. Contrast in used to highlight the vessels in the body so they will show up bright on the image. The contrast is injected through an IV that is inserted by either a tech or a nurse. Most scans were done on the chest, abdomen or pelvis but I also seen a few soft tissue neck scans and head scans. CT does both out patients and inpatients. They have a busy schedule and is very hard for them to stay on track. It doesn’t take much for them to fall behind. I enjoyed working in CT and cannot wait to go back. All the techs that we were working with were very nice and willing to help. They also taught us the basics to using a CT machine. I got select the protocol for the scan that was ordered, scan t he scout image and set the margins for the actual CT scan. They also showed me how to load up the injector with the appropriate amount of contrast and saline water. The contrast that they most commonly use is Omnipaque 350. My two favorite techs to work with were Melissa and Merikay. Melissa was very helpful and talked me through the steps from pulling up the patient, selecting the proper protocol and starting the scout image. I also got to log the amount of contrast that was injected and got toShow MoreRelatedElectromagnetic Fields And Its Effects On Human Society Essay1801 Words   |  8 PagesResonance Imaging (MRI) EENG 3303 College of Engineering Department of Electrical Engineering University of Texas at Tyler Houston, TX 29/11/2016 Adrian Acuna Abstract Magnetic resonance imaging (MRI) is a noninvasive medical test that physicians use to diagnose and treat medical conditions.  MRI  uses a powerful magnetic field, radio frequency pulses and a computer to produce detailed pictures of organs, soft tissues, bone and virtually all other internal body structures.

Detailed staging using high resolution magnetic resonance imaging (MRI) enables the selection of patients that require pre/ post-operative therapy for tumor regression. This information can be used to select neoadjuvant therapy and adjuvant therapy in those patients with poor prognosticRead MoreX Ray Versus Ct For Traumatic Paediatric Cervical Spine Imaging : What Guidance Do Clinicans Have?2983 Words   |  12 PagesX-RAY VERSUS CT FOR TRAUMATIC PAEDIATRIC CERVICAL SPINE IMAGING: WHAT GUIDANCE DO CLINICANS HAVE? Introduction: Evidence shows that road traffic accidents are the most common cause of paediatric cervical spine (c-spine) injury, with many dying at the scene (Booth, 2012). On presentation to the hospital, assessment of the paediatric patient requires recognition of subtle signs and symptoms, often in the setting of distracting injuries (Jones, Anderson and Noonan, 2011).

It will look at the scientific principles. Comparing the risks and hazards associated with each modality when examining pregnant patients. Risk reduction and safety will be discussed. Scientific Principles Computed Tomography CT is cross-sectional image acquisition using the x-ray beam transmission measurements.

MRI also takes longer than CT, possibly precluding imaging of critically ill, thermally unstable and uncooperative pediatric patients and more often requires onsite physician monitoring to assure diagnostic image quality. Finally, MRI is limited
