Early Radiologic Diagnosis of Pulmonary Infection in Febrile Neutropenic Patients: A Comparison of Serial Chest Radiography and Single CT Chest

Table 2

Summary of consensus chest films and CT chest compared to the clinical diagnosis of early pulmonary infection.

Early pulmonary infection		Clinical positive (n = 48)	Clinical negative (n = 59)
Chest film	Radiological active (n = 39)	24	15	PPV 61%
	No radiological active (n = 68)	24	44	NPV 64%
Early pulmonary infection		Clinical positive (n = 11)	Clinical negative (n = 15)
CT chest	Radiological active (n = 19)	10	9	PPV 45.8%
	No radiological active (n = 2)	1	6	NPV 100%

PPV, positive predictive value; NPV, negative predictive value.
