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: The brain morphology and structure were normal, with no abnormal density shadows in the brain parenchyma, and no significant abnormalities in FDG uptake.
The ventricular system was enlarged, with widening of the sulci, fissures, and cisterns.
The ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, with no significant abnormalities.
The right maxillary sinus mucosa was 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 structurally normal, and the bilateral parapharyngeal spaces were clear with no abnormal FDG uptake.
Both palatine tonsils showed physiological uptake.
The laryngopharynx morphology and structure were normal.
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 abnormal FDG uptake.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region; FDG metabolism was normal.
A soft tissue mass with indistinct borders and irregular edges, measuring approximately 6.4 4.9 cm, was observed in the left upper lobe adjacent to the mediastinum.
FDG metabolism was elevated, with an SUVmax of 5.9, indicating corresponding tracheal obstruction.
Adjacent large blood vessels were involved and surrounded, with scattered linear shadows around the mass.
Multiple solid nodules were also observed in both lungs, with relatively clear borders; the largest nodule had a long diameter of approximately 0.3 cm, and no abnormal FDG uptake was observed.
The bronchus in the posterior segment of the right lower lobe was slightly dilated, and the bronchial wall in the right middle lobe was also slightly thickened; no abnormal FDG uptake was observed.
Scattered linear shadows were observed in both lungs; no abnormal FDG uptake was observed.
The pleura was slightly thickened bilaterally, but there was no pleural effusion or pneumothorax.
Several lymph nodes were observed in the mediastinum, the largest with a short diameter of approximately 0.6 cm.
FDG metabolism was increased, with SUVmax = 1.9.
The cardiac silhouette appeared normal.
The liver showed no obvious abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Plain CT scan showed no obvious abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
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 or size, with no thickening of the gallbladder wall and no abnormal 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 abnormal FDG uptake.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
A punctate calcification was observed in the left kidney, with no abnormal FDG uptake.
The right kidney is normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma.
The renal pelvis, calyces, and ureter are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging shows no obvious abnormalities.
The esophagus is not dilated, and the wall is not significantly thickened or swollen; FDG uptake is not increased.
The stomach is poorly filled, but the wall is not significantly thickened; FDG uptake is not significantly abnormal.
Multiple small sac-like shadows with high density are visible around the ascending colon; FDG uptake is not abnormal.
The prostate is normal in size and uniform in density; FDG uptake is not abnormally increased.
The bladder is generally full, and no obvious positive stones are seen.
Multiple lymph nodes are seen in both inguinal regions, the largest with a short diameter of approximately 0.8 cm; some show increased FDG metabolism, SUVmax = 1.4.
A small amount of fluid-density shadow is seen in the tunica vaginalis of the left testis.
Scoliosis, partial vertebral marginal osteophyte formation, L3/4, L4/5, and L5/S1 intervertebral disc bulges, FDG uptake normal.
Left ribs 1-10 show discontinuity with localized angular deformity and bone ridge formation, FDG uptake normal.

Impression

1. a. A space-occupying lesion in the left upper lobe of the lung, adjacent to the mediastinum, with increased FDG metabolism, consistent with lung cancer with surrounding obstructive inflammation. b. Multiple chronic inflammatory micronodules in both lungs, mild bronchial dilatation in the right lower and middle lobes, and a few post-inflammatory remnants in both lungs. Slight pleural thickening bilaterally. Reactive hyperplasia of mediastinal lymph nodes.

2. Small renal calculus in the left kidney. Multiple reactive hyperplasia of bilateral inguinal lymph nodes. Small amount of hydrocele in the left testis.

3. Multiple diverticula in the ascending colon.

4. Scoliosis with osteophyte formation. L3/4, L4/5, and L5/S1 intervertebral disc bulges. Old fractures of the left 1st-10th ribs.

5. Age-related brain changes; MRI recommended. Minor inflammation of the right 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.
