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 scan revealed: multiple nodules and patchy low-density areas in the brain; FDG showed multiple focal uptakes (SUVmax = 11.0).
Midline structures were centered.
Both eyes were symmetrical and showed no obvious abnormalities.
The left ethmoid sinus mucosa was slightly thickened, but the sinus wall was intact.
The nasopharyngeal wall was not thickened, and FDG uptake was normal.
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were normal, and the bilateral parapharyngeal spaces were clear with normal FDG uptake.
The 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.
A roughly round low-density shadow measuring approximately 3.6 2.7 cm was visible in the left lobe of the thyroid gland; the capsule was relatively smooth, and it protruded into the pleural cavity, showing increased FDG uptake (SUVmax = 4.9).
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region; FDG metabolism was normal.
A patchy soft tissue shadow with indistinct borders was observed in the right lower lobe, surrounded by scattered small nodules and short linear shadows; the boundary with the adjacent pleura was unclear; FDG metabolism was increased, SUVmax = 5.9.
Multiple small nodules were observed in both lungs, the largest approximately 0.5 cm in diameter.
A few linear shadows were observed in the apical-posterior segment of the left upper lobe and the lateral-basal segment of the left lower lobe; FDG uptake was normal in all these areas.
No pleural thickening was observed bilaterally; a small amount of arc-shaped fluid density shadow was observed in the right pleural cavity.
Multiple enlarged lymph nodes were observed in the right hilum, pretracheal space, aortic window, subcarinal region, and left paraesophageal region; the largest had a short diameter of approximately 1.5 cm; FDG metabolism was increased, SUVmax = 16.9.
Some arterial walls showed calcification.
No esophageal dilation was observed; no significant thickening or mass was observed in the esophagus; FDG uptake was normal.
Bilateral breasts are relatively dense, and FDG metabolism is normal.
The liver's shape and size are normal, with smooth borders, no widening of the hepatic fissure, and no obvious abnormal density shadows in the liver parenchyma on plain CT scan; FDG uptake is normal.
The main portal vein is not significantly widened, and there is no dilation of intrahepatic or extrahepatic bile ducts.
The gallbladder's shape and size are normal, the gallbladder wall is not thickened, and local FDG uptake is normal.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormal FDG uptake.
The spleen's shape, size, density, and FDG uptake are normal.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows in the parenchyma; the renal pelvis, calyces, and ureters are not widened, and FDG uptake is normal.
Bilateral adrenal glands show no obvious abnormalities on contrast.
The stomach is poorly distended, with no obvious thickening of the stomach wall and no obvious abnormal FDG uptake.
The intestines are poorly distended, with no obvious thickening or mass in the intestinal wall; FDG uptake is physiological.
The uterus is small, with no abnormal density shadows, and no abnormally increased FDG uptake.
No abnormal FDG metabolism was observed in the bilateral adnexa.
The bladder is generally full, with no obvious positive stones.
No enlarged lymph nodes were observed in the abdominal cavity, pelvic cavity, or retroperitoneal region, and FDG metabolism was normal.
No obvious fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies and L4/5 disc bulging.
Focal FDG uptake was observed in the right scapula, right 1st anterior rib, right 4th rib, right 10th posterior rib, left 8th posterior rib, bilateral iliac bones, left upper femur, and multiple vertebral bodies, with SUVmax = 8.8 and partial bone destruction.

Impression

1. a. Space-occupying lesion in the lower lobe of the right lung, with increased FDG metabolism, suggestive of lung cancer. b. Multiple lymph node metastases in the right hilum and mediastinum. Small amount of pleural effusion on the right side. c. Multiple intracranial metastases. Multiple bone metastases throughout the body. d. Multiple metastases in both lungs.

2. A few fibrotic lesions in the left lung. Some arterial wall calcification.

3. Nodular goiter in the left lobe of the thyroid gland is highly probable; ultrasound re-examination is recommended to rule out malignancy.

4. Inflammation of the left ethmoid sinus.

5. Spinal osteophyte formation, L4/5 intervertebral disc bulge.

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.
