“…In previous studies, it has been shown that CT scan is especially useful in detection of mediastinal lymphadenopathy [13][14][15][16], nodules, small cavities [10] and areas of scar [13]; however, the results of current study are not exactly the same. In this study while it is demonstrated that mediastinal lymphadenopathy, especially on the right side, is detected significantly better by thoracic CT scan than chest X-ray, the same results are not found for cavity, nodule and scar changes.…”

Background:Imaging is the mainstay of diagnostic criteria in tuberculosis (TB) diagnosis, especially in children; however, the exact role of chest X-ray (CXR) and thoracic CT scan (TCT) still remains controversial. The aim of this study is to compare digital chest X-ray and thoracic CT scan in childhood tuberculosis. Materials and Methods: In this retrospective comparative study, 38 children under 15 years old with proved diagnosis of TB who were admitted to Massih Daneshvari hospital during 2010 to 2012. Digital chest X-ray and spiral thoracic CT was performed before starting medication. Results: Direct smear for acid-fast bacillus was positive only in 38%. Positive tuberculin skin test was seen in 51% of the cases. Chest X-ray was normal in 36.8% of children, while CT scan was negative only in 21%. Overall sensitivity of thoracic CT scan and chest X-ray were 78.9% and 63.2%, respectively which show no significant difference. CT scan detected lymphadenopathy, nodule/nodular infiltration, collapse and pleural effusion/ thickening significantly better than chest X-ray; however, there was no significant difference between CXR and TCT in detection rate of consolidation/ground glass opacity, bronchiectasis, cicatricial volume loss and cavity/abscess. Conclusions: This study proposed that investigation of children suspicious of tuberculosis by digital chest X-ray is still of great value. It seems that thoracic CT scan in children suspected of tuberculosis infection can be limited only to investigation of complications in selected patients.

“…Çalışmamızda da benzer şekilde en sık belirlenen bulgular lenfadenopati ve konsolidasyon olup, sırasıyla %64 ve %22 oranında saptandı. Diğer önemli bir bulgu çalışmamız da %20 oranında granülom olup, literatürde görülme oranları %1-7 arasındadır (24,25) . Akciğer TB'sinde radyolojik granülom görünümü çoğunlukla erken dönem bulgusu olup, primer enfeksiyon imajı olarak karşımıza çıkmaktadır.…”

“…CT is more sensitive than chest radiography for making the diagnosis and characterizing the cases of both subtle and disseminated parenchymal dis-ease and mediastinal lymphadenopathy that are predominantly situated in peripheral subregions. CT is also more sensitive for the evaluation of cases of tuberculous effusion, emphysema, and bronchopleural fistula that are not evident on plain radiographs [8][9][10][11][12]. The increased use of CT, and in particular helical CT, for higher resolution and higher definition of internal structures for the diagnosis of suspected PTB before treatment, has raised concerns about the radiation dose and associated cancer risk for exposed individuals.…”

Abstract:The preference for computed tomography (CT) for the clinical assessment of pulmonary tuberculosis (PTB) infections has increased the concern about the potential risk of cancer in exposed patients. In this study, we investigated the correlation between cancer risk and radiation doses from different CT scanners, assuming an equivalent scan protocol. Radiation doses from three 16-slice units were estimated using the CT-Expo dosimetry software version 2.4 and standard CT scan protocol for patients with suspected PTB infections. The lifetime risk of cancer for each scanner was determined using the methodology outlined in the BEIR VII report. Organ doses were significantly different (P < 0.05) between the scanners. The calculated effective dose for scanner H2 is 34% and 37% higher than scanners H3 and H1 respectively. A high and statistically significant correlation was observed between estimated lifetime cancer risk for both male (r 2 = 0.943, P < 0.05) and female patients (r 2 = 0.989, P < 0.05). The risk variation between the scanners was slightly higher than 2% for all ages but was much smaller for specific ages for male and female patients (0.2% and 0.7%, respectively). These variations provide an indication that the use of a scanner optimizing protocol is imperative.
