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 patchy low-density area in the right temporoparietal lobe, with no significant abnormalities in FDG uptake.
The ventricular system was enlarged, with slight widening of the sulci and fissures.
The ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical and without significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, 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 morphology and structure of the laryngopharynx were normal.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland showed uneven density in the left and right lobes, with calcifications within.
A ring-shaped calcified nodule, approximately 1.7 cm in diameter, was observed in the left lobe, with uneven FDG uptake and an SUVmax of 3.2.
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 measuring approximately 7.8 6.1 8.7 cm was observed in the posterior segment of the right upper lobe, with irregular margins, septate internal structure, and visible gas and fluid density shadows; FDG uptake was increased (SUVmax = 9.9).
Multiple nodular or linear thickenings were observed in the right pleura, involving the right costal and diaphragmatic pleura, with the thickest point approximately 2.1 cm; FDG metabolism was increased (SUVmax = 12.3); an arc-shaped fluid density shadow was observed in the right pleural cavity.
Enlarged lymph nodes were observed in the right hilum and mediastinum, pretracheal and posterior to the vena cava; the largest cross-section was approximately 4.1 3.7 cm; FDG metabolism was increased (SUVmax = 10.1).
Calcification was observed in the walls of the aorta and coronary arteries.
The cardiac silhouette was normal.
No esophageal dilation, significant wall thickening, or mass was observed; FDG uptake was normal.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissures.
Plain CT scan revealed 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 and 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 cystic lesion approximately 2.5 cm in diameter was observed in the left kidney, with no abnormal FDG metabolism.
The right kidney was normal in shape and size, with no obvious abnormal density shadows in the parenchyma, and no widening of the renal pelvis, calyces, or ureter.
FDG uptake was normal.
Bilateral adrenal gland imaging showed no obvious abnormalities.
The stomach was poorly distended.
A soft tissue mass measuring approximately 5.4 4.5 cm was observed in the cardia region, with relatively clear borders, a broad base attached to the gastric wall, and heterogeneous internal density with visible liquefactive necrosis.
FDG uptake was increased, with SUVmax = 7.4.
The intestines were poorly distended, but no significant thickening or mass was observed in the intestinal wall; FDG uptake was physiological.
The prostate was of normal size and homogeneous density, with no abnormally increased FDG uptake.
The bladder was generally full, with no obvious positive stones.
No enlarged lymph nodes were observed in the abdominal cavity, pelvis, or retroperitoneal region; FDG metabolism was normal.
A small amount of fluid-density shadow was observed in the bilateral testicular tunica vaginalis.
The spinal alignment was normal, with some vertebral body margin osteophytes; FDG uptake was normal.
No abnormal FDG metabolism was observed in the entire skeletal system.

Impression

1. a. Right upper lobe posterior segment lesion, increased FDG metabolism, suggestive of malignancy, please correlate with clinicopathology. b. Multiple metastases to the right pleura, small amount of right pleural effusion. Multiple lymph node metastases to the right hilum and mediastinum. c. Lobe-shaped low-density area in the right temporoparietal lobe, lack of FDG uptake, primarily suggestive of encephalomalacia, metastasis to be ruled out, contrast-enhanced MRI recommended. Age-related brain changes.

2. Soft tissue mass in the gastric cardia region, increased FDG metabolism, suggestive of stromal tumor (malignant), please correlate with clinicopathology.

3. Partial calcification of the aorta and coronary artery walls.

4. Uneven density with calcification in the left and right lobes of the thyroid gland, uneven FDG uptake, suggestive of nodular goiter, ultrasound and related laboratory tests recommended.

5. Left renal cyst. Small amount of hydrocele in both testes.

6. Spinal osteophyte.

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.
