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, and resting, a whole-body PET/CT scan was performed.
The whole-body scan showed:Normal brain morphology and structure, with punctate low-density lesions in the deep bilateral cerebral regions; no significant abnormalities in FDG metabolism.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the bilateral ventricles were symmetrical, and there was no midline shift.
Normal morphology and contour of the bilateral eyeballs; clear retrobulbar structures; symmetrical optic nerves; no abnormal FDG metabolism.
No thickening of the paranasal sinus mucosa; intact sinus walls.
No thickening of the nasopharyngeal wall; no stenosis of the bilateral pharyngeal recesses or Eustachian tube openings; normal structures of the infratemporal fossa and pterygopalatine fossa; clear bilateral parapharyngeal spaces; no abnormal FDG metabolism.
Physiological FDG metabolism was observed in the oropharynx and laryngopharynx.
No abnormal contrast was observed in the bilateral parotid and submandibular glands.
The thyroid gland is normal in shape and size, with uniform density, and FDG metabolism is normal.
No significantly enlarged lymph nodes were seen in the bilateral deep cervical spaces, submandibular region, and submental region.
Slightly increased pulmonary irregularities were observed.
An irregular soft tissue density mass was seen near the hilum of the left lower lobe, with a cross-sectional size of approximately 6.5*3.5*5.1cm.
FDG metabolism was increased, with SUVmax=7.3.
The boundary between the mass and the left pulmonary artery was unclear, and the corresponding bronchus was truncated.
A few patchy shadows were seen distal to the lesion.
Scattered solid nodules were observed in both lungs, with regular shape and clear borders, with a long diameter of approximately 0.3-0.5cm.
FDG uptake was normal.
Several calcifications were observed in both lungs.
A few linear and flocculent density shadows were also seen in both lungs, with FDG metabolism normal.
Cystic lucent shadows were seen in the subpleural region of both lungs.
The pleura was slightly thickened bilaterally, but there was no pleural effusion or pneumothorax.
Left hilar and mediastinal (pretracheal, post-vena cava, pulmonary artery window, subcarinal) lymph nodes are visible, the largest being approximately 2.9 cm in short diameter, with increased FDG metabolism and SUVmax = 8.1.
Cardiac findings are normal.
Some arterial walls show calcification.
Liver morphology and size are normal, with smooth borders and no widening of the hepatic fissure.
CT scan reveals multiple low-density nodules in the liver parenchyma with smooth edges, the largest being approximately 3.3 cm in long diameter, with absent FDG metabolism.
Subcapsular calcification is present in the right lobe of the liver.
The main portal vein is not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts is observed.
Gallbladder morphology and size are normal, with no thickening of the gallbladder wall.
A slightly high-density shadow is seen at the gallbladder fundus, with no local FDG metabolism abnormalities.
Pancreas morphology is normal, with no significant abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no significant FDG metabolism abnormalities.
The spleen is normal in shape and size, with a slightly low-density lesion within the splenic parenchyma, measuring approximately 0.8*0.7cm in cross-section.
FDG metabolism is absent.
Cystic low-density lesions are seen in the parenchyma of both kidneys, with clear borders; the largest is approximately 2.3cm in long diameter.
FDG metabolism is absent.
Fine punctate high-density shadows are seen in the left renal pelvis.
No widening of the renal pelvis, calyces, or ureters is observed, and FDG metabolism is normal.
No significant abnormalities are seen on bilateral adrenal gland imaging.
No esophageal dilatation is observed, and no significant thickening or mass is seen in the esophageal wall.
FDG metabolism is normal.
Gastric distension is poor, with slight thickening of the gastric wall and a slightly increased FDG metabolism (SUVmax = 2.3).
Intestinal distension is poor, with multiple high-density shadows seen in the colon.
FDG metabolism is normal.
The prostate is enlarged, with a transverse diameter of approximately 5.4 cm.
High-density shadows are seen within the parenchyma, and FDG metabolism is normal.
The bladder is poorly filled, and no obvious positive stones are seen within it.
Fluid density shadows are present in both scrotums, with absent FDG metabolism.
No enlarged lymph nodes are seen in the abdomen, pelvis, or retroperitoneal region.
No obvious effusion is seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies.
L4/51 intervertebral disc bulge is present, with normal FDG metabolism.
Increased bone density at the relative margins of the L5/S1 vertebral bodies and narrowing of the intervertebral space are observed.
Dense bone shadows are present within the S1 vertebral body, with normal FDG metabolism.
Decreased bone density was observed in the upper humerus, scapula, clavicle, sternum, multiple ribs, multiple vertebrae and their appendages, sacrum, multiple pelvic areas, and upper femur on both sides.
Increased FDG metabolism was also observed, with SUVmax = 6.6.

Impression

1. a. A mass near the hilum in the lower lobe of the left lung, with increased FDG metabolism, suggestive of central lung cancer with surrounding obstructive inflammation, possibly involving the left pulmonary artery. Please correlate with clinicopathology. b. Metastasis to the left hilar and mediastinal lymph nodes. Multiple bone metastases throughout the body. c. Chronic bronchitis-like changes in both lungs. Scattered chronic inflammatory nodules (solid) in both lungs; please correlate with CT follow-up. Several calcifications in both lungs. A few post-inflammatory remnants in both lungs. Paraseptal emphysema in both lungs. Slight pleural thickening bilaterally. Partial arteriosclerosis. d. Lacunar infarcts deep in the brain; MRI follow-up is recommended.

2. Multiple liver cysts. Possible gallstones. Possible small splenic angioma.

3. Bilateral renal cysts, small kidney stone in the left kidney. Benign prostatic hyperplasia with calcification. Bilateral hydrocele.

4. Slightly thickened gastric wall, mildly elevated FDG metabolism; please correlate with gastroscopy. Multiple high-density shadows in the colon; please correlate with clinical findings.

5. Degenerative changes in the spine. L4/5 intervertebral disc bulge. L5/S1 vertebral endplate inflammation. Small bony islands within the S1 vertebral body.

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.
