Conclusions: Ultrasound is superior to oral cholecystogram for diagnosing cholelithiasis, and radionuclide scanning is the test of choice for acute cholecystitis. However, sensitivities and specificities are somewhat lower than commonly reported. We recommend estimates that are midway between the adjusted and unadjusted values.
An ultrasound uses sound waves, a transducer, and a computer to create images of the internal organs. It is most well-known as a tool used by obstetricians, but it has more applications than that. It is also used in treatment, particularly ultrasou
student entering the A.C.E. program is given diagnostic tests to determine skill and concept mastery. The tests assist the evaluator in determining the student’s academic needs in each subject. After the student completes the testing, he is given curriculum that meets and challenges him at his performance level. Four academic areas are tested: math Levels 1-9, English Levels 1-8, reading Levels 1-8 (science, social studies, Bible Reading, and Literature and Creative Writing), and spelling Levels 2-9. These tests cover basic skills normally mastered before high school. When weak areas are evident from the testing, the appropriate gap PACEs are prescribed to strengthen specific weaknesses. After completing the gap PACEs, the student progresses at his performance level. If he demonstrates mastery at all levels of testing, he has the ability to function at his chronological grade level. The aceconnect Diagnostic Test is free and requires one-time registration for your entire school or homeschool.
