Perbedaan Cardiothoracic Ratio (CTR) Normal antara Proyeksi Standar Foto Toraks dengan Proyeksi Anterio Posterior (AP) Supine Ekspirasi Maksimal

---

Cardiothoracic Ratio (CTR) used to determine the widening of the heart in radiology measurement. CTR is measured by comparing the heart witth to cavum thoracales in thorax PA projection. However, not all patients can be examined by chest X-ray examination with standard position (PA erect, maximal inspiration) because of the ambulatory detect that make the patient can not stand in erect position. Unfortunately, cliniclans need the information about IL. There is a different normal index between CTR in standard position of chest x-ray and AP projection, supine and maximal expiration. With AP projection supine, maximal expiration. This was a cross sectional study conducted in Radiology Installation Dr. Sardjito Hospital, Jogjakarta on August to October 2008. Subjects that recruited in study in this study have no radiolgic abnomalities, the radiolgraph Thorax result were examined and recorded in PA erect and AP supine projection. Then measurement of the CTR done in those two projection. Data were analyzed by a comparative descriptive method that compared the mean value in PA erect and AP supine group using independent samples t-test. From 150 subject, 74 were men (49.3%) and 76 were women (50-796) Mean age betwen these subject were 39.8+1247 years old. The ratio of CTR in pa erect projection. Maximal inspiration was 0.43 ±0.03 and in Ap supine projecttion 0.52±0.03 (p
