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 eyes were symmetrical, with no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
The nasopharynx was of acceptable morphology, with increased FDG metabolism (SUVmax = 4.4).
The pharyngeal recesses were symmetrical, and there was no stenosis of the Eustachian tube openings.
The infratemporal and pterygopalatine fossae were structurally normal, and the parapharyngeal spaces were clear, with no abnormalities in FDG uptake.
The 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 no abnormalities were observed in FDG metabolism.
A bronchial stenosis/occlusion is observed in the medial segment of the right middle lobe, with a consolidation lesion measuring approximately 6.2 5.5 cm.
The borders are relatively clear but irregular, and the boundary with the adjacent pleura is indistinct.
A nodule with increased FDG uptake is seen near the hilum (SUVmax = 16.7, long axis approximately 2.1 cm).
The distal consolidation lesion shows increased FDG uptake (SUVmax = 12.5).
Multiple focal air-containing cystic cavities are seen in the upper lobes of both lungs.
Scattered linear and flocculent density shadows are also seen in both lungs, with no abnormal FDG uptake.
Multiple solid nodules with relatively clear borders are seen in both lungs, the largest being approximately 0.3 cm in long axis.
Multiple small round high-density shadows are also seen in both lungs, with no abnormal FDG uptake.
No pleural thickening is observed bilaterally, and there is no pleural effusion or pneumothorax bilaterally.
Enlarged right hilar lymph nodes, approximately 1.2 cm in short diameter, with increased FDG metabolism (SUVmax = 16.5).
Multiple lymph nodes were also observed in the mediastinum, the largest approximately 1.0 cm in short diameter, some with higher density, and increased FDG metabolism (SUVmax = 5.9).
Partial calcification was observed in the walls of the aorta and coronary arteries.
No esophageal dilatation, wall thickening, or mass was observed; FDG uptake was not increased.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Plain CT scan showed no significant abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
The main portal vein showed no significant widening, and no dilatation 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 is normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is normal.
The spleen's shape, size, density, and FDG uptake are normal.
A punctate high-density shadow is visible in the left kidney, with no abnormal FDG metabolism.
A low-density lesion with a long diameter of approximately 1.0 cm is seen in the right kidney; the renal pelvis, calyces, and ureter are not widened, and FDG uptake is normal.
The right adrenal gland shows no obvious abnormalities on contrast.
A slightly low-density nodule is visible in the left adrenal gland, with relatively clear borders, measuring approximately 1.3 0.9 cm, with a CT value of approximately -13 HU; FDG uptake is normal.
The stomach is poorly distended, with thickened mucosa in the fundus and body, and increased FDG uptake (SUVmax = 6.0).
The intestines are poorly distended; no obvious thickening or mass is seen in the intestinal wall, and FDG uptake is physiological.
The prostate gland is of acceptable morphology, with punctate dense shadows visible internally.
FDG uptake is not abnormally increased.
The bladder is generally full, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdomen, pelvis, or retroperitoneal region, and FDG metabolism is normal.
No significant fluid accumulation is seen in the abdomen or pelvis.
The spinal alignment is normal, with some vertebral body margin osteophytes, mild wedge-shaped changes in the L1 vertebral body, and bulging of the L3/4, L4/5, and L5/S1 intervertebral discs.
FDG uptake is normal.
No abnormal FDG metabolism is observed in the entire skeletal system.

Impression

1. a. A mass in the right middle lobe of the lung with increased FDG metabolism, highly suggestive of lung cancer with atelectasis; bronchoscopy recommended. b. Reactive hyperplasia of the right hilar and mediastinal lymph nodes; CT follow-up recommended to rule out other possibilities. Partial calcification of the aorta and coronary artery walls. c. Emphysema in the upper lobes of both lungs, multiple chronic inflammatory micronodules in both lungs, and multiple calcifications in both lungs.

2. A slightly low-density nodule in the left adrenal gland, with no abnormal FDG uptake, highly suggestive of an adenoma; contrast-enhanced MRI recommended. Right renal cyst. Small crystals in the left kidney. Prostatic calcification.

3. Thickening of the gastric fundus and body mucosa with increased FDG metabolism, suggestive of inflammation or physiological uptake; clinical correlation recommended.

4. Increased FDG metabolism in the nasopharynx, suggestive of inflammation or physiological uptake; please correlate with clinical findings and, if necessary, undergo specialist examination.

5. Spinal osteophyte formation, mild wedge-shaped deformity of the L1 vertebral body. L3/4, L4/5, and L5/S1 intervertebral disc bulges.

6. Age-related brain 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.
