Whole-body 18F-FDG PET/CT scan in a patient with Lung Cancer taken from the PETWB-REP dataset. The following English report (translated from original Chinese) is taken verbatim from the public dataset and has not been modified or otherwise checked for accuracy (see the end for citation).

Findings

After fasting and intravenous injection of 18F-FDG, a whole-body PET/CT scan was performed.
The whole-body scan showed: The brain morphology and structure were normal, with no abnormal density shadows in the brain parenchyma, and no significant abnormalities in FDG uptake.
The ventricles, sulci, fissures, and cisterns were widened, with symmetrical bilateral ventricles and no midline shift.
Both eyeballs were symmetrical, with no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, and FDG uptake was normal.
The bilateral pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear with no abnormal FDG uptake.
Both palatine tonsils showed physiological uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx morphology and structure were normal.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Increased translucency in both lungs, accompanied by bullae formation.
An irregular soft tissue mass with spiculated and lobulated margins was seen in the apical-posterior segment of the left upper lobe, measuring approximately 2.9*1.6cm; FDG metabolism was increased, SUVmax=15.1.
A solid nodule with spiculated and lobulated margins was seen in the posterior-basal segment of the right lower lobe, traction on the pleura; measuring approximately 2.0*2.0cm; FDG metabolism was increased, SUVmax=4.4.
Multiple small solid nodules were found in both lungs, with clear borders, long diameters approximately 0.3-0.9cm; FDG uptake was normal.
Scattered calcifications, patchy opacities, and linear opacities were observed in both lungs.
No pleural thickening was seen bilaterally; no pleural effusion or pneumothorax was observed bilaterally.
Multiple lymph nodes were observed in the bilateral pulmonary hila, pretracheal space, para-aortic arch, aortic window, and subcarinal region, the largest measuring approximately 0.6 cm in short diameter.
FDG metabolism was increased, with an SUVmax of 3.2.
Calcification of some arterial walls was observed (including the coronary arteries).
The cardiac silhouette appeared normal.
The esophagus showed no dilation, wall thickening, or mass; FDG uptake was not increased.
The liver's shape and size were normal, with smooth borders and no widening of the hepatic fissure.
A low-density lesion approximately 2.1 cm in long diameter was seen in the right lobe of the liver on plain CT scan, with clear borders and absent FDG uptake.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts.
The gallbladder's shape and size were normal, with no wall thickening and no abnormal local FDG uptake.
Pancreas: Normal morphology, no obvious abnormal density shadows seen in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG uptake.
Spleen: Normal morphology, size, density, and FDG uptake.
Kidneys: Normal morphology and size, no obvious abnormal density shadows seen in the parenchyma, no widening of the renal pelvis, calyces, or ureters, and no obvious abnormalities in FDG uptake.
Adrenal glands: No obvious abnormalities seen on contrast imaging.
Stomach: Poor distension, no obvious thickening of the stomach wall, and no obvious abnormalities in FDG uptake.
Intestinal: Poor distension; post-rectal cancer surgery, no obvious thickening or mass seen in the intestinal wall at the surgical site, and FDG uptake is physiological.
Prostate: Normal morphology and size, uniform density, and no abnormal FDG metabolism seen.
Bladder wall: No abnormal thickening, and no obvious positive stones seen within.
Bilateral hydrocele.
Localized dilation of the abdominal aorta, approximately 3.7 cm in diameter, with no abnormalities observed in FDG uptake.
No enlarged lymph nodes were observed in the abdominopelvic region or retroperitoneal area.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment is normal, with some vertebral body margin osteophytes and L3/4, L4/5, and L5/S1 intervertebral disc bulges.
Systemic bone FDG metabolism was normal.

Impression

1. a. Masses in the apical-posterior segment of the left upper lobe and the posterior-basal segment of the right lower lobe with increased FDG metabolism, highly suggestive of lung cancer; please confirm with pathology. b. Multiple solid nodules in both lungs, FDG uptake normal, suggestive of chronic inflammatory nodules; please follow up with CT to rule out other confounding nodules. Scattered chronic inflammation and remnants in both lungs. Emphysema and bullae in both lungs. c. Reactive hyperplasia of hilar and mediastinal lymph nodes in both lungs. Calcification of some arterial walls (including coronary arteries).

2. Postoperative rectal cancer surgery, no obvious signs of tumor recurrence in the surgical area.

3. Cyst in the right lobe of the liver. Bilateral hydrocele.

4. Localized enlargement of the abdominal aorta, suggestive of aneurysm; CTA follow-up is recommended.

5. Partial vertebral osteophyte formation. L3/4, L4/5, L5/S1 intervertebral disc bulge.

6. Age-related brain changes.

This case is from PETWB-REP, a curated dataset of whole-body 18F-FDG PET/CT scans and corresponding radiology reports from 490 patients with a broad spectrum of malignancies. The data were retrospectively collected from patients who underwent clinically indicated whole-body 18F-FDG PET/CT scans at the Shanghai Universal Medical Imaging Diagnostic Center between 2021 and 2024.
