A 76-year-old female presented with rheumatic mixed mitral valve pathology. A chest X-ray revealed massive cardiomegaly and splaying of the carina (Fig. 1). CT scan showed gross isolated left atrial (LA) enlargement (Fig. 2a), which was plicated from within (Fig. 2b). A mitral valve replacement and LA reduction was performed but she died of an operative complication. Fig. 1. Chest X-ray shows m...

In order to model photon attenuation and detector resolution variation as a depth-dependent convolution for efficient reconstruction of quantitative SPECT, a central-ray approximation is necessary. This work investigates the impact of the approximation upon reconstruction accuracy and computational efficiency. A patient chest CT image was acquired and converted into an object-specific attenuati...

Radiation dose reduction in pediatric X-ray imaging is especially important because of children radiation sensitivity. For any radiographic examination performed at a fixed radiographic tube potential, the patient absorbed dose is directly proportional to the value of milliampere-seconds (mAs) selected by the operator. Nevertheless, reducing X-ray exposure has the unavoidable disadvantage of in...

WHAT A TEAM! Napoleon preferred lucky generals, and Thorax has lucky Editors in Chief because we have a great team of deputy editors, associate editors, production staff and editorial board. A former Editor in Chief (it is said!) used to write to authors to say either “I am sorry, but the Associate Editor has recommended rejection of your manuscript” or “I am pleased to tell you I that have acc...

Congenital hiatal hernia with herniation of stomach into thorax is not uncommon in children but this herniation is usually seen in midline or on left side. However, right sided intrathoracic stomach with its organoaxial torsion secondary to congenital hiatal hernia is a rare occurrence. Barium meal examination is essential for its diagnosis but plain x-ray of the abdomen can arouse the suspicio...

A case of spontaneous pneumothorax occurring at the end of labour in a healthy 17-year-old primigravida is described. Its occurrence was accompanied by marked surgical emphysema of the face, neck, arms and thorax. The patient had had previous thyroid surgery and was coincidentally found to have bilateral cervical ribs on chest X-ray. Previously described cases are reviewed, and the management d...

We described the case of a 36-year-old Turkish female with an extralobar pulmonary sequestration who suffered from chest and back pain for five years without any evidence of pulmonary infection. A chest X-ray showed an area of opacity behind the cardiac silhouette in the lower area of the left hemithorax. A CT scan of the thorax with intravenous contrast showed a 9 x 7 cm in size ovoid mass wit...
