Hysterosalpingogram (HSG)

Image
 The hysterosalpingogram or HSG is a simple x-ray procedure performed using fluoroscopy with intermittent still images for documentation in general the actual procedure takes three to five minutes the hsg is a relatively low-risk procedure but does result in ovarian radiation exposure greater than a pelvic CT scan thus repetitive 8 sets hsg procedures should be avoided and the radiation exposure time  Demonstrates performance of an HSG notice the slow filling of the uterine cavity with radio-opaque dye while the uterus is positioned perpendicular to the x-ray beam subsequent fill of the fallopian tubes are visualized with a free spill into the peritoneal cavity unfortunately many women have preconceptions that the HSG is a very painful test there is no question that the discomfort is influenced by the experience of the operator an HSG is performed with the installation of a radio-opaque contrast into the uterine cavity installation devices include instruments that fit into the...

Instrumentation of Fluoroscopy

Image
Instrumentation of Fluoroscopy  The components of this fluoroscopic imaging chain from this illustration you can see has a generator x-ray tube collimator filtration a table for the patient and the patient grid image intensifier optical coupling video camera and a monitor finally to visualize the image let's go step by step on this fluoroscopic imaging chain the x-ray generator the work of the accelerate generator is to enable selection of kilovolt edge and tube current that is Kaylyn MA for the accelerator the kV Mme can be altered using automatic brightness control it's called ABC now why do we need an automatic brightness control it maintains the overall image brightness at a constant level as the imagined inspire is panned across different parts of the body next, we move on to the x-ray tube requires high tube loading for extended views because fluoroscopy is a continuous process it's not like the exposures which are taken in routine radiography it can have a grid contr...

Contrast Media types

Image
 Contrast media is and the types of contrast media in the  radiographic contrast in our radiographic imaging series we learned the differences in tissue thickness and other characteristics of tissues determine how much radiographic contrast is produced this means that when there is a high difference in the structure of tissues like how bones and fat are different great contrast is recorded on the image a great difference in densities on the image now what happens when there is a low difference between different anatomical structures and you need an image contrast media is employed contrast media or artificial media that are used in delineating or outlining tissues that naturally have a low subject contrast this implies body parts with structures that are similar in appearance Contrast media increases the subject contrast in these body parts examples of parts that we commonly use contrast media for include the digestive system the urinary system the reproductive system and the ...
