Abstract:
We report a case of incidental multiple focal uptakes of Tc-99m MDP in both the lungs without lung parenchymal abnormality. A 15-year-old girl who had no symptoms or history of pulmonary disorder was referred for Tc-99m MDP bone scintigraphy to evaluate temporomandibular joint disorders. Bone scintigraphy showed multiple focal uptakes in the chest. Single photon emission computed tomography/computed tomography scan performed on the same day showed that abnormal uptakes were located in both the lungs and no abnormalities in the corresponding pulmonary parenchymal sites. Abnormal uptakes resolved on bone scintigraphy after 7 days.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Fundamental Principles of PET
Positron Emission Tomography
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body being...
Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
