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

Under fasting conditions, an intravenous injection of 18F-FDG was administered, followed by rest.
Whole-body PET/CT imaging revealed: A few punctate low-density shadows were observed in the deep bilateral cerebral regions; no abnormal density shadows were seen in the remaining brain parenchyma.
FDG uptake was normal.
The ventricles, sulci, fissures, and cisterns were widened; the ventricles were symmetrical, and there was no midline shift.
The lens of the left eye was unclear; no obvious abnormalities were seen in the right eye.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; FDG uptake was normal.
The bilateral pharyngeal recesses were symmetrical; there was no stenosis of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the bilateral parapharyngeal spaces were clear, and FDG uptake was normal.
Bilateral palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
The thyroid gland is normal in shape and size, with uniform density, and FDG uptake is normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
An irregular mass measuring approximately 7.3 6.5 cm was observed in the anterior segment of the right upper lobe near the hilum, with increased FDG metabolism (SUVmax = 10.7), corresponding bronchial obstruction, and multiple patchy, nodular, and blurred shadows in the surrounding subpleural region, with increased FDG metabolism (SUVmax = 8.6).
The mass is poorly demarcated from the adjacent pericardium and great vessels.
Several solid micronodules, approximately 0.2?.4 cm in long diameter, with clear borders, were observed in both lungs, and FDG metabolism was normal.
Multiple scattered patchy and linear lesions were also observed in both lungs, with normal FDG metabolism.
A small amount of pleural effusion was observed on the right side, accompanied by partial atelectasis of the right lower lobe.
Enlarged lymph nodes were observed in the right hilum and behind the vena cava, the largest measuring approximately 1.2 cm in short diameter, with increased FDG metabolism (SUVmax = 5.9).
Several slightly enlarged lymph nodes, approximately 0.9 cm in short diameter, were observed in the right upper mediastinum, beside the trachea, at the aortopulmonary window, and below the carina, with increased FDG metabolism (SUVmax = 3.2).
Some arterial walls showed calcification.
The esophagus was not dilated, and the wall was not significantly thickened or swollen; FDG uptake was not increased.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissures.
Plain CT scan showed no significant abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
The main portal vein was not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape or size, and the gallbladder wall was not thickened; local FDG uptake was normal.
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.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows in the parenchyma; punctate dense shadows are seen in the right kidney, while the left 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 filled, with slight thickening of the antral wall and slightly increased FDG uptake (SUVmax = 2.3).
The intestines are poorly filled, with continuous increased FDG metabolism in parts of the colon and rectum (SUVmax = 5.3).
The prostate is full in shape, with punctate dense shadows inside, and no abnormal FDG metabolism.
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.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulges.
The sacral canal was dilated, containing a cystic lesion approximately 4.0 2.3 cm in size, with absent FDG uptake.

Impression

1. a. A mass near the hilum in the anterior segment of the right upper lobe, with unclear boundaries from the adjacent pericardium and great vessels. Increased FDG metabolism is consistent with lung cancer, accompanied by obstructive pneumonia. A small amount of pleural effusion on the right side with partial atelectasis in the right lower lobe. b. Metastasis to the right hilar and pretracheal vena cava lymph nodes. Possible metastasis to the right upper mediastinal paratracheal, aortopulmonary window, and subcarinal lymph nodes. c. Several solid micronodules of chronic inflammation in both lungs. Chronic inflammation and old lesions in the remaining lungs. Calcification of some arterial walls.

2. A few ischemic lesions in the deep bilateral brain, indicative of senile encephalopathy. Unclear visualization of the left lens.

3. Small renal calculi in the right kidney. Calcification of the prostate.

4. Slight thickening of the gastric antrum wall and mildly increased FDG uptake suggest chronic gastritis; continuous increased FDG metabolism in parts of the colon and rectum suggest inflammatory or physiological uptake. Follow-up gastroscopy and colonoscopy are recommended.

5. Cervical, thoracic, and lumbar spondylosis. L4/5 and L5/S1 intervertebral disc bulges. Sacral canal cyst.

6. A few ischemic lesions in the deep bilateral cerebral regions; age-related encephalopathy.

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.
