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 brain regions, with no abnormal FDG metabolism.
Enlargement of the ventricles, sulci, fissures, and cisterns was observed.
The bilateral ventricles were symmetrical, with no midline shift.
Both eyeballs were symmetrical, with no obvious abnormalities.
A small cystic lesion was seen in the left maxillary sinus, with intact sinus walls.
The nasopharyngeal wall was not thickened, and FDG uptake was normal.
The bilateral pharyngeal recesses were symmetrical, with no stenosis of the Eustachian tube openings.
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.
The laryngopharynx was normal in morphology and structure.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The thyroid gland was normal in shape and size, with uniform density, and no abnormal FDG uptake.
No enlarged lymph nodes were seen in the left neck, and FDG metabolism was normal.
An irregular mass measuring approximately 5.1 5.6 6.5 cm was observed in the left upper lobe near the hilum, with increased FDG metabolism (SUVmax = 16.4).
There was also bronchial obstruction in the left upper lobe.
A few linear and punctate lesions were observed in the remaining lungs, with normal FDG metabolism.
A small amount of pleural effusion was present on the left side.
Multiple enlarged lymph nodes were observed in the right submandibular region, right supraclavicular fossa, left hilum, pretracheal space, para-aortic arch, aortopulmonary window, subcarinal region, peripancreatic region, and retroperitoneum, the largest with a short diameter of approximately 3.0 cm, showing increased FDG metabolism (SUVmax = 13.9).
A small amount of pericardial effusion was present.
Calcification of some arterial walls (including the coronary arteries) was observed.
The esophagus showed no dilation, no significant thickening or mass in the esophagus, and no increased FDG uptake.
The liver had an irregular outline, and multiple low-density masses and nodules were observed within the liver, the largest with a long diameter of approximately 4.2 cm, showing increased FDG metabolism (SUVmax = 4.9).
The gallbladder showed no abnormalities in shape or size, and the gallbladder wall was not thickened; local FDG uptake was normal.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma; the main pancreatic duct was not widened; and FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
A spleen-like density nodule with a long diameter of approximately 1.5 cm was observed around the spleen; FDG uptake was normal.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma; the renal pelvis, calyces, and ureters were not widened; and FDG uptake was normal.
Two low-density nodules were observed in the bilateral adrenal glands, the larger one located on the left, measuring approximately 1.3 1.5 cm; FDG metabolism was increased, with SUVmax = 14.9.
The stomach was poorly distended; the stomach wall was not significantly thickened; and FDG uptake was normal.
The intestines were poorly distended; the intestinal wall was not significantly thickened or lumped; FDG uptake was physiological.
The prostate was normal in size, with punctate calcifications observed; and FDG uptake was not abnormally increased.
The bladder was generally full, with no obvious positive stones.
No obvious fluid accumulation was observed in the abdomen or pelvis.
The spinal alignment was normal, with osteophyte formation at the margins of some vertebral bodies and bulging of the L4/5 and L5/S1 intervertebral discs.
Bone destruction was observed in the bilateral scapulae, bilateral humeral shafts, multiple bilateral ribs, sternum, multiple vertebral bodies and appendages of the spine, sacrum, multiple areas of the pelvis, and the upper segments of both femurs.
FDG metabolism was elevated, with SUVmax = 15.9, and some rib cortical discontinuities were observed on the right side.

Impression

1. a. A mass near the hilum of the left upper lobe, with increased FDG metabolism, suggestive of central lung cancer. Multiple lymph node metastases in the right submandibular region, right supraclavicular fossa, left hilum, mediastinum, peripancreatic region, and retroperitoneum. Bilateral adrenal metastases. Multiple liver metastases. Multiple bone metastases throughout the body (pathological fractures of some ribs on the right side). b. Small amount of pleural effusion on the left side. Small amount of pericardial effusion. Calcification of some arterial walls (including coronary arteries). c. A few chronic inflammatory lesions and old lesions in both lungs.

2. Accessory spleen. A few calcifications in the prostate.

3. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulges.

4. Intracerebral ischemic lesions, age-related brain changes; follow-up MRI is recommended. Submucosal cyst of the left maxillary sinus.

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.
