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: Brain morphology and structure were normal, with a small, round, low-density area in the left basal ganglia; FDG uptake was not significantly abnormal.
The ventricular system was enlarged, with slight widening of the sulci, fissures, and cisterns; the ventricles were symmetrical, and there was no midline shift.
Both eyes were symmetrical, with no obvious abnormalities.
The left maxillary sinus mucosa was slightly thickened, but the sinus wall was intact.
FDG uptake in the nasopharynx was increased (SUVmax = 2.8); the pharyngeal recesses were symmetrical; there was no stenosis of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear, and FDG uptake was not abnormal.
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 is normal in shape and size, with uniform density, and no abnormalities were observed in FDG uptake.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region, and FDG metabolism was normal.
A soft tissue mass measuring approximately 3.8 2.1 cm was observed in the posterior basal segment of the left lower lobe, with relatively clear borders and slightly irregular edges.
The corresponding bronchus was involved and truncated.
FDG metabolism was increased, with SUVmax = 9.4, and scattered streaks were observed around it.
The left lower hilum was enlarged, and a soft tissue mass measuring approximately 4.9 3.9 cm was observed, with relatively clear borders and irregular edges.
The internal density was uneven and calcification was observed, with increased FDG metabolism (SUVmax = 8.9).
The boundary between the mass and the surrounding hilar structures was unclear, and the adjacent pleura was also poorly adhered.
Multiple small nodules were observed in both lungs, the largest being approximately 0.3 cm in length, and FDG metabolism was normal.
Bilateral pleural thickening, with calcification on the right and a small amount of fluid density shadow in the left pleural cavity.
Multiple enlarged lymph nodes are seen in the right hilum, pretracheal space, para-aortic arch, aortopulmonary window, and below the carina, the largest with a short diameter of approximately 3.6 cm, showing increased FDG metabolism (SUVmax = 8.1).
The cardiac silhouette is normal.
The esophagus is not dilated, and the wall is not significantly thickened or swollen; FDG uptake is not increased.
The liver is normal in shape and size, with smooth borders and no widening of the hepatic fissure.
A cystic lesion is seen in the left lateral lobe of the liver, with a long diameter of approximately 0.2 cm; 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 is normal in shape and size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is not significantly abnormal.
The spleen is normal in shape, size, density, and FDG uptake.
A punctate dense shadow is seen in the left kidney, and a small cystic lesion with a long diameter of approximately 0.2 cm is also seen in the left renal parenchyma.
FDG metabolism is not abnormal.
The right kidney is normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureter are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging is normal.
The stomach is poorly distended, with slight thickening of the antral wall.
FDG metabolism is increased, with SUVmax = 3.2.
FDG uptake in the distal rectum is increased, with SUVmax = 5.4.
The prostate is of acceptable shape, with punctate dense shadows inside.
FDG uptake is not abnormally increased.
The bladder was generally full, with no obvious positive stones observed.
A small amount of fluid-density shadow was seen in the tunica vaginalis of both testes.
Enlarged lymph nodes were seen posterior to the pancreas and adjacent to the inferior vena cava; the former was larger, approximately 1.2 cm, with increased FDG metabolism (SUVmax = 4.9).
The spinal alignment was normal, with some vertebral body margin osteophytes.
There were disc bulges at L2/3, L3/4, L4/5, and L5/S1, but FDG uptake was normal.
Increased FDG metabolism was observed in the bilateral shoulder joint capsules (SUVmax = 1.9).

Impression

1. a. A mass in the lower lobe of the left lung with increased FDG metabolism, highly suggestive of lung cancer with surrounding obstructive changes; please correlate with clinicopathology. Multiple lymph node metastases in the bilateral hilar, mediastinal, posterior pancreatic body, and perivena cava areas. Small amount of pleural effusion on the left side. b. Multiple chronic inflammatory micronodules in both lungs are highly probable; follow-up CT is recommended. Bilateral pleural thickening with right-sided calcification.

2. Increased FDG metabolism in the nasopharynx, suggesting possible inflammation; specialist follow-up is recommended. Inflammation of the left maxillary sinus.

3. Small cyst in the left lateral lobe of the liver. Small kidney stone and cyst in the left kidney. Calcification in the prostate. Small amount of hydrocele in both testes.

4. Slightly thickened gastric antral wall with increased FDG uptake, highly suggestive of gastritis; follow-up gastroscopy is recommended. Increased FDG metabolism in the distal rectum, suggesting hemorrhoids or inflammatory uptake.

5. Spinal degenerative changes. L2/3, L3/4, L4/5, L5/S1 intervertebral disc bulge. Bilateral frozen shoulder.

6. Small softening lesion in the left basal ganglia region, age-related brain changes; 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.
