Feasibility of fast non local means filter in pediatric chest x-ray for increasing of pulmonary nodule detectability with 3D printed lung nodule phantom
The ribs show a wide range of normal and pathologic radiographic appearences as well as congenital variations. Intrathoracic ribs are isolated and rare anomalies. They are usually super-numerary, more often right-sided, and involve the middle part of the thorax. We describe a case with intrathorasic rib abnormality mimicking a peripheral metastatic lung nodule in the plain chest x-ray and emphasize the use of coronal and sagittal reformatted images in thorasic imaging. Utilisation of multiplanar reformatted images in chest computerised tomography increase diagnostic quality.
The pediatric chest X-ray (CXR) provides a wealth of useful information. In most instances, clinicians are seeking more definitive information regarding the lungs. Findings can be subtle or obvious, but difficult to notice. “Tunnel vision” permits the human brain to focus on areas of interest, only to miss other important findings. This chapter discusses the clinical entities that can be identified on a pediatric CXR and presents examples of most of these entities. The CXR is best read in a methodical manner focusing one’s attention on the heart, lungs, aorta, mediastinum, bones, neck, abdomen, and the periphery of the CXR.
There is paucity in literature on the use of endobronchial ultrasound through esophagus (EUS-B) for the diagnosing thyroid gland lesions. We report the first case of colloid goiter diagnosed using EUS-B- FNA technique. A 77-year-old man presented with ophthalmic symptoms and an incidental finding of lung nodule on chest x-ray. The computed tomography of thorax revealed a left upper lobe nodule and an oval shaped left paratracheal lesion near left pole of thyroid gland. EUS-B- FNAC was performed which lead to the diagnosis of colloid goiter.
