Define Problemsf. Differentia Diagnosesg. PlanOutline of Current LectureI. Common Diagnostic TestsII. ImagingCurrent LectureI. Common Diagnostic Testsa. CDC = complete blood counti. White blood cells - high in the beginning of an infectionii. Red blood cellsb. Chemistry paneli. Proteinsii. Ions - sodium, potassiumiii. Glucoseb. Urinei. Specific gravity - concentration of urine1. Low = kidney problemsii. Cellsiii. BacteriaII. Imaginga. Can be expensive and can be cheapb. Radiographi. Using X-raysThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.ii. Generates an imageiii. Images internal structureiv. Dense structures are brighterv. Safety1. Ionizing radiation2. can damage genetic material in spermatozoa and ovum3. Injury tends to be cumulativeii. Digital X-Rays1. Enhances the contrast2. Manipulates the image3. Allows image to be saved, stored, retrieved, and transmittedii. Interpretation1. Dense tissues do not allow x-rays to penetrate2. Bones appear white3. The soft tissue appears grey (cannot tell the difference between muscle and blood)ii. Least expensiveb. Computed tomography - CTi. Uses x-rays and computer technology to generate an imageii. At all veterinary teaching hospitalsiii. Patient must remain motionlessiv. General anesthesia requiredv. Can tell the differences between bone and soft tissue; however cannot tell details in the soft tissueb. Ultrasonographyi. Images produced using ultrasound is called a sonogram1. Uses sound waves2. Image is displayed in real time3. Allows to visual:a. Beating heartsb. Fetal movement2. Save for operator3. Does not require sedationii. Used for:1. Echocardiography2. Diagnose
