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: a few punctate low-density shadows in the deep bilateral cerebral regions; no abnormal density shadows were seen in the remaining brain parenchyma, and FDG uptake was normal.
The ventricles, sulci, fissures, and cisterns were widened, with symmetrical bilateral ventricles and no midline shift.
The eyeballs were symmetrical bilaterally, with no obvious abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening, and FDG uptake was normal.
The pharyngeal recesses were symmetrical bilaterally, 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.
The palatine tonsils showed physiological uptake.
The laryngopharynx showed no abnormalities in morphology or structure.
The parotid and submandibular glands showed no abnormal density shadows bilaterally.
The thyroid gland was normal in shape and size, with uniform density, and FDG uptake was normal.
No enlarged lymph nodes were seen bilaterally in the neck, and FDG metabolism was normal.
An irregular nodule measuring approximately 1.5 2.0 1.3 cm was observed in the basal segment of the right lower lobe, with spiculated margins and increased FDG metabolism (SUVmax = 12.1).
Several small solid nodules, approximately 0.2-0.3 cm in long diameter, with clear borders, were observed in both lungs, with normal FDG metabolism.
A few scattered linear and punctate lesions were also observed in both lungs, with normal FDG metabolism.
No pleural thickening was observed bilaterally.
Multiple slightly enlarged lymph nodes were observed in the bilateral hilum, pretracheal space, para-aortic arch, aortopulmonary window, subcarinal region, and right supraclavicular fossa, with the largest having a short diameter of approximately 1.1 cm.
FDG metabolism was increased (SUVmax = 7.1).
The cardiac silhouette was normal.
Calcification of some arterial walls (including coronary arteries) was observed.
No esophageal dilatation, significant wall thickening, or mass was observed, and FDG uptake was not increased.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissures.
Several cystic lesions were observed within the liver, the largest being approximately 1.2 cm in length, with absent FDG uptake.
A nodular dense shadow was seen at the edge of the right lobe of the liver.
The main portal vein showed no obvious widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape and size, with no thickening of the gallbladder wall and no abnormalities in local FDG uptake.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG uptake.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
The left kidney showed punctate dense shadows, while the right kidney was normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureter showed no widening, and no obvious abnormalities in FDG uptake were observed.
Bilateral adrenal glands showed no obvious abnormalities on contrast.
The stomach was poorly distended, with no obvious thickening of the gastric wall and no obvious abnormalities in FDG uptake.
Intestinal distension was poor, with no obvious thickening or mass in the intestinal wall; FDG uptake was physiological.
The prostate was of normal size, with punctate calcifications observed; FDG uptake was not abnormally increased.
The bladder was generally full, with no obvious positive stones.
A nodular calcification was observed in the vesicorectal space.
Increased FDG uptake was observed in the perineal region, with an SUVmax of 11.1 and an uptake length of approximately 1.9 cm.
No enlarged lymph nodes were observed in the abdominal cavity, pelvis, or retroperitoneal region; FDG metabolism was normal.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral margin osteophytes, and pneumothorax and bulging of the L4/5 and L5/S1 intervertebral discs; FDG uptake was normal.
Decreased bone density and cortical discontinuity were observed in the left 5th and 6th ribs; FDG metabolism was increased, with an SUVmax of 11.0.
Increased FDG metabolism was observed around the left hip joint, with an SUVmax of 3.1.

Impression

1. a. A mass in the basal segment of the right lower lobe, with increased FDG metabolism, suggestive of lung cancer; please correlate with clinicopathology. b. Reactive hyperplasia of the hilar, mediastinal, and right supraclavicular lymph nodes is highly probable, with metastasis to be ruled out. Significant changes following fracture of the left 5th and 6th ribs, with metastasis to be ruled out; please correlate with clinical history.

2. Several small, solid, chronic inflammatory nodules in both lungs. A few chronic inflammations and old lesions in both lungs. Calcification of some arterial walls (including coronary arteries).

3. Multiple liver cysts. Intrahepatic calcifications. Small kidney stone in the left kidney. Calcifications in the prostate. Calcifications in the vesicorectal space. Increased FDG uptake in the perineal area; please correlate with clinical examination.

4. Degenerative changes in the spine. Pneumothorax and bulging of the L4/5 and L5/S1 intervertebral discs. Inflammation around the left hip joint.

5. A few ischemic lesions in the deep bilateral brain regions, suggestive of age-related brain changes; follow-up MRI is recommended.

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.
