Contrast RADIOGRAPHIC IMAGING

 Contrast RADIOGRAPHIC IMAGING A high overall radiographic density or a low overall radiographic density also holds true for contrast an image can offer only little differences in density between different structures and be known as a low contrast image on the other hand a great difference in density between different structures can exist and this is known as a high contrast image the reason why a low contrast image gives little difference in densities is because there are so many densities present on a low contrast image ranging from light to dark this long range of densities gives the low contrast image the term long-scale contrast, on the other hand, a great difference in densities exists on a high contrast image because only a few densities are recorded on these images this is why high contrast images are also known as short-scale contrast images it might be tempting to assume that high contrast radiographic images are good and low contrast images are bad.   A high contras...

Arthrography

Arthrography  The indications contraindications and complications of arthrography describe pertinent Anatomy imaged on an arthrogram discuss pre-procedure preparation and assessment of a patient undergoing arthrography identify radiation protection and technical factors used during arthrography identify contrast agents used and their indications for an arthrogram described the patient positioning and procedural steps of an arthrogram of the hip and shoulder discuss post-procedure care and instructions for patients following an arthrogram procedure the patients.  The performance of the procedure a focused physical examination of the patient's affected joint may be performed labs are usually not needed on patients who are not on anticoagulant therapy for patients on warfarin therapy pro Stompin time or PT partial thromboplastin time or PTT INR and platelet count can be ordered, patients in anticoagulant therapy do not need to stop their medications prior to the procedure informe...

Advanced Abdominal Ultrasound

Ultrasound criteria of appendix ultrasound  >6mm Noncompressible structure  Pain with transducer pressure Presence of free fluid Signs of obstruction  The criteria again are going to be an appendix that's enlarged greater than 6 millimeters it is a non-compressible structure the people will have pain with transducer pressure there may be the presence of free fluid and there may be signs of obstruction or ileus so the way that we scan. we can use the linear probe if the patient size allows us and we can start by mowing the lawn at the edge of the liver or we can start down by the iliac crest if we start at the edge of the liver we're going to look for the gas in the colon as seen in this scan right here and we will follow that down until we see a tubular noncompressible structure and here we also see hyperechoic fat suggesting inflammation or stranding around the appendix just deep to the appendix we will see in this clip the iliopsoas muscle right here you can see the ...
