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: Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; no significant abnormalities were observed in FDG uptake.
The ventricular system was slightly enlarged; widening of the sulci, fissures, and cisterns was observed.
The ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical and showed no significant abnormalities.
The left maxillary sinus mucosa was thickened, with high-density shadows visible; the sinus wall was intact.
The nasopharyngeal wall was not thickened; FDG uptake was normal.
The pharyngeal recesses were symmetrical; there was no narrowing of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the bilateral parapharyngeal spaces were clear; and FDG uptake was normal.
Both palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
The thyroid gland was normal in morphology and size, with uniform density; and FDG uptake was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region; FDG metabolism was normal.
A patchy consolidation was observed in the right upper lobe adjacent to the mediastinum, surrounded by scattered flocculent density shadows, with indistinct boundaries from the adjacent pleura.
A focal foci of increased FDG, approximately 2.2 1.6 cm in size, with an SUVmax of 16.2, was observed at the bronchial opening in the right upper lobe.
Scattered linear shadows were also observed in both lungs; FDG metabolism was normal.
After pericardiocentesis, the soft tissue of the chest wall in the surgical area was slightly thickened, with increased FDG metabolism (SUVmax = 8.0).
The pericardium was thickened, containing fluid-density shadows, with localized soft tissue thickening and increased FDG metabolism (SUVmax = 7.2).
A small amount of fluid-density shadow was observed in the right pleural cavity, and the left pleura was slightly thickened.
Multiple enlarged lymph nodes were observed in the right hilum, mediastinum, and left supraclavicular fossa, the largest with a short diameter of approximately 0.7 cm; FDG metabolism was increased (SUVmax = 9.9).
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
A nodular shadow with relatively clear borders, measuring approximately 1.0 0.7 cm, was observed subcutaneously on the left side of the shoulder and back, with increased FDG metabolism (SUVmax = 4.7).
Both breasts were relatively dense, and FDG metabolism was normal.
The liver showed no significant abnormalities in shape or size, with smooth liver margins, no widening of the hepatic fissure, and no significant abnormal density shadows in the liver parenchyma on plain CT scan; FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder wall showed thickening, with short, linear high-density shadows visible locally; FDG uptake was normal.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma; the main pancreatic duct was not widened; FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is normal.
The left adrenal gland is slightly enlarged, with no abnormal FDG uptake.
The right adrenal gland shows no obvious abnormalities on contrast.
The stomach is poorly distended, with no obvious thickening of the gastric wall, and FDG uptake is normal.
The intestines are poorly distended, with no obvious thickening or mass in the intestinal wall, and FDG uptake is physiological.
The uterus is normal in shape, with no abnormal density shadows, and FDG uptake is normal.
No abnormal FDG metabolism is seen in the bilateral adnexa.
The bladder is generally full, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdominal cavity, pelvis, or retroperitoneal region, and FDG metabolism is normal.
No obvious fluid accumulation is seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with some vertebral body margin osteophytes, L3/4, L4/5, and L5/S1 intervertebral disc bulges, and pneumothorax visible in the L5/S1 intervertebral disc.
FDG uptake is normal.
Bone density changes and increased FDG metabolism are visible in the C2, T3, T5, T11, and T12 vertebral bodies, with SUVmax = 13.4.
Increased FDG metabolism is also observed in the proximal right femur, with SUVmax = 4.8.

Impression

1. a. A mass in the right upper lobe of the lung with increased FDG uptake, suggestive of right upper lobe lung cancer with obstructive changes; multiple lymph node metastases in the right hilum, mediastinum, and left supraclavicular fossa; multiple bone metastases; pericardial metastases with pericardial effusion; subcutaneous metastases in the left shoulder and back. b. Changes after pericardiocentesis. Inflammation of the left chest wall soft tissue is highly probable. c. A few fibrotic lesions in both lungs. Right pleural effusion, slight thickening of the left pleura.

2. Senile cerebral atrophy. Inflammation of the left maxillary sinus, likely due to fungal infection.

3. Chronic cholecystitis, gallstones. Left adrenal hyperplasia.

4. Spinal degeneration, L3/4, L4/5, L5/S1 intervertebral disc bulge, L5/S1 intervertebral disc pneumodegenerative 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.
