EXAM: CT CHEST WITHOUT CONTRAST

HISTORY: Lung Nodules

TECHNIQUE: CT was performed from lung apex to the lung base on the multislice CT scanner without the use of intravenous contrast. Sagittal and coronal reformatted images were performed. Coronal MIP images were performed.

The total DLP was 280 mGy-cm and the CTDI was 8 mGy. Low dose protocols were performed.

One or more of the following dose reduction techniques were used: automated exposure control, adjustment of the mA and/or kV according to patient size, use of iterative reconstruction technique. A total of 0 CT (Computed Tomography) examinations and 0 myocardial perfusion studies have been performed on this patient over the past 12 months. Counts as indicated include examinations performed within our network.

COMPARISON: 4/29/2022

FINDINGS:

Visualized Inferior Neck: Visualized inferior neck soft tissue structures are unremarkable.  Visualized thyroid gland is unremarkable.

Vasculature: Prominent ascending aorta measures 4.1 cm in diameter. Main pulmonary trunk is within normal limits.

Aortic Atherosclerosis: Present
Coronary vascular calcification: Mild
Assigned values based on visual inspection. Consider calcium score CT for objective measurements and risk stratification.

Mediastinum: Heart size within normal limits. No pericardial effusion. Airway is patent. Esophagus is unremarkable.

Lymphadenopathy: Prominent mediastinal lymph nodes some which are partially calcified. Prominent subcarinal node measures up to 10 mm in short axis.

Chest Wall: Chest wall soft tissues are unremarkable. Degenerative changes of thoracic spine noted. No aggressive destructive osseous lesions. Ribs are intact.

Visualized Abdomen: Unremarkable

Lungs: Anterior left upper lobe masslike consolidation measures 6.5 x 3.8 cm with adjacent parenchymal stranding. Additional focal groundglass opacity in left upper lobe measures 7 mm, series 4-51. Several scattered groundglass nodules seen in the right lung ranging from 4 to 5 mm, with a representative nodule in series 4-99. No sizable pleural effusions.

IMPRESSION:
1. Masslike consolidation left upper lobe, new since prior exam. Correlate with PET/CT for further evaluation.

HCC/RAF: Yes
