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 images showed: Normal brain morphology and structure, with patchy low-density shadows in the deep cerebral regions bilaterally; FDG uptake was not significantly abnormal.
Enlargement of the ventricles, sulci, fissures, and cisterns was observed; the ventricles were symmetrical bilaterally, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with clear retrobulbar structures and no abnormal density shadows; FDG uptake was normal.
Thickening of the right maxillary sinus mucosa was observed.
No thickening of the nasopharyngeal wall was observed; FDG uptake was normal.
The pharyngeal recesses were symmetrical bilaterally, with no stenosis of the Eustachian tube openings.
The infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear; FDG uptake was normal.
The palatine tonsils showed physiological uptake bilaterally.
The laryngopharynx was normal in morphology and structure.
The thyroid gland was normal in morphology and size, with slightly uneven density; FDG uptake was normal.
A nodular shadow measuring approximately 1.0*0.5cm was observed in the deep lobe of the right parotid gland, with elevated FDG metabolism (SUVmax = 14.8).
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
A solid plaque lesion with cavity was observed in the apical-posterior segment of the left upper lobe, measuring approximately 3.0*2.9cm, with elevated FDG metabolism (SUVmax = 13.6).
Multiple solid nodules were observed in both lungs, the largest being approximately 2.0*1.0cm in size located subpleurally in the right lung, some with elevated FDG metabolism (SUVmax = 2.7).
Multiple linear and honeycomb shadows were observed in both lungs, predominantly subpleural, with elevated FDG metabolism (SUVmax = 2.6).
Slight thickening of the pleura was observed bilaterally.
No pleural effusion or pneumothorax was observed bilaterally.
Calcification of some arterial walls was observed.
Multiple lymph nodes were observed in the left hilum, pretracheal space, para-aortic arch, main pulmonary window, and subcarinal region, the largest with a short diameter of approximately 1.2 cm.
Some showed increased FDG metabolism, with an SUVmax of 9.2.
The cardiac silhouette appeared normal.
The esophagus showed no dilation, wall thickening, or mass; FDG uptake was not increased.
The liver was normal in shape and size, with smooth borders and no widening of the hepatic fissure.
Plain CT scan showed decreased liver parenchymal density (CT value approximately 44 HU); FDG uptake was normal.
The main portal vein was not significantly widened, and intrahepatic and extrahepatic bile ducts were not dilated.
This patient had undergone cholecystectomy.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma; the main pancreatic duct was not widened; FDG uptake was normal.
The spleen was normal in shape, size, density, and FDG uptake.
Both kidneys were normal in shape and size, with scattered small cystic lesions; FDG uptake was normal; the left renal pelvis was dilated.
Bilateral adrenal glands showed no significant abnormalities on contrast imaging.
The stomach is poorly filled, with thickened gastric walls and slightly elevated FDG metabolism (SUVmax = 3.0).
Post-rectal cancer surgery, bowel preparation is poor, with continuous FDG metabolism elevation in the ascending colon, transverse colon, and descending colon (SUVmax = 5.5).
The prostate is of normal size and uniform density, with no abnormally elevated FDG uptake.
The bladder is generally full, with no obvious positive stones.
Calcification of the tunica vaginalis is present on the right side.
No enlarged lymph nodes are seen in the abdominal cavity, pelvis, or retroperitoneal region.
No significant fluid accumulation is seen in the abdominal or pelvic cavities.
A localized nodular FDG uptake elevation is observed in the right gluteus medius muscle (SUVmax = 6.8), measuring approximately 1.2 x 0.7 cm.
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies and L4/5 and L5/S1 intervertebral disc bulges.
Multiple areas of bone destruction are present in the T8 vertebral body, L5 spinous process, and sacrum, with elevated FDG metabolism (SUVmax = 7.2).

Impression

1. a. Solid plaque lesion with increased FDG metabolism in the posterior segment of the left upper lobe, suggestive of malignancy; please confirm the diagnosis with pathology. b. Metastasis to some lymph nodes in the left hilum and mediastinum. c. Metastasis to the right gluteus medius muscle; metastasis to the deep lobe of the right parotid gland is pending; follow-up is recommended. Multiple bone metastases to the T8 vertebral body, L5 spinous process, and sacrum. d. Interstitial inflammation in both lungs. Chronic inflammatory nodules in both lungs are highly probable; please follow up with CT scans. Slight thickening of the pleura bilaterally. Calcification of some arterial walls.

2. Post-rectal cancer surgery, no obvious signs of tumor recurrence. Physiological or inflammatory uptake of the stomach and part of the colon; endoscopic follow-up is recommended.

3. Lacunar infarcts in the deep brain bilaterally; age-related brain; no obvious abnormalities seen on cranial FDG imaging; no obvious abnormal FDG metabolic lesions seen in either eye. Enhanced MRI is recommended for follow-up to rule out occult lesions. Right maxillary sinusitis.

4. Mild fatty liver. Post-cholecystectomy.

5. Bilateral renal cysts. Left renal pelvis dilation. Right testicular tunica vaginalis calcification.

6. Spinal degenerative changes. L4/5 and L5/S1 intervertebral disc bulges.

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.
