Abstract:
A 56-year-old female presented with intermittent hemoptysis and was diagnosed with lung cancer. 18F-fluorodeoxyglucose positron emission tomography/CT for staging revealed hypermetabolic liver (hot liver), uptake in the mediastinal lymph nodes and reduced uptake in the kidneys. Unexpectedly, liver biopsy findings were consistent with tuberculous infection. Following the intensive phase of antituberculous treatment, repeat CT revealed significant resolution of the mediastinal lymph nodes making the lung cancer Stage 1 (T1 lesion). She underwent left lower lobectomy as a definitive surgical treatment. Positron emissiontomography/CT scan in this patient was considered to be a hepatic superscan since it revealed a hot liver.

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...

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...
