Radiology as a Medical Science In 1895 Roentgen began experiments at the University of Würzburg with an electric current flow in a partially evacuated glass tube known as a cathode-ray tube. He noticed that‚ whenever the tube was in operation‚ a piece of barium platino cyanide in line with it gave off light. According to Roentgen “the interaction of electrons striking the tube’s glass wall formed an unknown radiation that caused the fluorescence”. He called the mysterious phenomenon X radiation‚ or X rays

anhydrous Barium Sulphate precipitate by gravimetric method. Gravimetric method is by the quantitative determination of the mass of anhydrous Barium Sulphate precipitate. Barium sulphate precipitate is form when Barium Chloride is added excessively to a hot given Sulphate solution slightly acidified with concentrated Hydrochloride acid. The white precipitate of hydrate Barium Sulphate formed is than digest‚ filtered out‚ washed and dried than cool down in a desiccator. Anhydrous Barium Sulphate is

Conductimetric Titration and Gravimetric Determination of a Precipitate Objective: * Measure the conductivity of the reaction between sulfuric acid and barium hydroxide * use conductivity values to determine equivalence point * measure mass of a product to determine equivalence point gravimetrically * calculate molar concentration of barium hydroxide solution Procedure: * First‚ combine 10.0 mL of the Ba(OH)2 solution with 50 mL of distilled water. Then‚ measure out 60 mL of 0.100

sulphate is determined quantitatively as barium sulphate by gravimetric analysis. This determination consists of slowly adding a dilute solution of barium chloride to a hot‚ unknown sulphate solution which is slightly acidified with concentrated hydrochloric acid. A white precipitate will formed and is then filtered off‚ washed with deionised water‚ dried in the oven and weighed as barium sulphate. The percentage of sulphate is calculated from the weight of barium sulphate. (B) Objective The purpose

diagnose juvenile polyposis when they see five or more polyps in the colon or rectum‚ when polyps appear in other parts of the digestive tract or family members have had them. A doctor seeing unexplained weight loss and fatigue in a patient may order a barium enema to reveal bleeding polyps. To rule out other disorders‚ they also test: Liver – Doctors check the liver’s health‚ when symptomatic patients complain of abdominal pressure or when discovering an abdominal mass‚ to rule out hepatic tumors and

Health Assessment Exam #4 Chapter 21: Abdomen (approx. 21 questions) 1. Aortic pulsation a. Normally‚ you may see the pulsations from the aorta beneath the skin in the epigastric area‚ particularly in thin persons with good muscle wall relaxation. b. Marked pulsation of aorta occurs with widened pulse pressure (e.g.‚ hypertension‚ aortic insufficiency‚ thyrotoxicosis) and with aortic aneurysm. c. lateral pulsation with aortic aneurysm pushes the examiner’s two fingers apart. 2.

Dysphagia depend on the tumor size‚ location‚ other structures involved‚ and the type of treatment. The most severe cases of dysphagia seemed to be worse in patients who were treated with chemoradiation. To diagnose dysphagia in patients‚ a Modified Barium Swallow (MBS) is conducted to help determine strategies to reduce aspiration as well as ways to improve swallowing function. These specific strategies include ideas such as postures‚ maneuvers‚ and other modifications (Pauloski‚

at my clinic. We seem to use our ultrasound and our gastrointestinal scope more frequently when we are concerned about a foreign body‚ mass‚ infection‚ gastrointestinal lining of the stomach etc. So‚ I chose to use a stuffed animal and administer barium via a gastrointestinal tube. If this would have been a real animal I would have chosen to have it fasted for at least 12 hours to ensure a completely empty stomach‚ intestines‚ and colon. Because I used a stuffed animal it is quite hard to see anything
