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; no abnormal density shadows were seen in the brain parenchyma; no significant abnormalities in FDG uptake were observed.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed; the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; the palatine tonsils were symmetrical bilaterally, and FDG uptake was physiological.
The laryngopharynx showed no abnormalities in morphology and structure.
The parotid and submandibular glands bilaterally showed normal morphology and density, and physiological FDG uptake was observed.
The thyroid gland was normal in morphology and size, with slightly uneven density; FDG metabolism was increased.
Small lymph nodes in the bilateral deep cervical spaces, submandibular, and submental regions were observed, showing increased FDG uptake (SUVmax = 5.1).
Post-operatively, a linear dense shadow was seen in the upper lobe of the right lung, surrounded by a few linear shadows; FDG metabolism was not abnormal.
Several small solid nodules were observed in both lungs, the largest being approximately 0.4 cm in diameter, with no abnormal FDG uptake.
Scattered linear lesions were present in both lungs, with no abnormal FDG uptake.
Slight localized thickening of the right pleura was observed, but there was no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
Slightly enlarged lymph nodes were visible in both axillae, the largest being approximately 0.8 cm in short diameter, with increased FDG uptake (SUVmax = 3.2).
The cardiac silhouette was normal.
The esophagus was not dilated, and the esophageal wall showed no significant thickening or mass; FDG uptake was not increased.
No significant masses or nodules were seen in either breast, and FDG metabolism was normal.
The liver showed no significant abnormalities in shape or size, with smooth borders, no widening of the hepatic fissure, and no significant abnormal density shadows in the liver parenchyma on plain CT scan; 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 is normal in shape and size, with no thickening of the gallbladder wall and no abnormal FDG uptake in the local area.
The pancreas is 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.
There is a local bulge on the medial border of the spleen, with no abnormal FDG uptake.
Both kidneys are normal in shape and size, with small low-density lesions in the renal parenchyma, no abnormal FDG metabolism, and no widening of the renal pelvis, calyces, or ureters, with no obvious abnormal FDG uptake.
The adrenal glands are thickened bilaterally with increased FDG uptake, SUVmax=2.5.
The stomach is adequately filled, with slight thickening of the walls of the gastric antrum and duodenal bulb, and increased FDG uptake, SUVmax=2.9.
The intestines are not adequately filled, with no local masses, and increased FDG uptake in the anal canal, SUVmax=2.9.
The uterus is normal in shape and size, with no abnormal density shadows and no abnormal FDG uptake.
There are no obvious abnormalities in the bilateral adnexa.
The bladder is poorly filled, with no obvious positive stones.
Numerous small lymph nodes were observed in the hepatogastric space, interhilar cavity, retroperitoneum, bilateral pelvic walls, and bilateral inguinal regions, showing increased FDG uptake (SUVmax = 2.5).
No significant fluid accumulation was observed in the abdomen or pelvis.
The spinal alignment was normal, with mild osteophyte formation at the margins of some vertebral bodies.
The cortical margins of the right 4th and 5th ribs were slightly irregular, and a high-density lesion was observed on the auricular surface of the right iliac bone.
Overall skeletal FDG uptake was normal.

Impression

1. a. Postoperative changes in the right upper lobe of lung cancer, no signs of tumor recurrence in the surgical area; b. Chronic inflammatory nodules in both lungs, follow-up CT recommended. Scattered post-inflammatory lesions in both lungs. Slight local thickening of the right pleura. Reactive hyperplasia of bilateral axillary lymph nodes.

2. Bilateral adrenal hyperplasia, possible small renal cysts, please follow up; local protrusion on the medial border of the spleen, possibly normal variation, please use ultrasound to rule out space-occupying lesions.

3. Reactive hyperplasia of lymph nodes in the hepatogastric space, interhilar cavity, retroperitoneum, bilateral pelvic walls, and bilateral inguinal regions.

4. Chronic inflammatory changes in the antrum of the stomach and duodenal bulb, hemorrhoidal changes, please use endoscopy for follow-up.

5. Mild vertebral osteophyte formation. Changes following fracture of the right 4th and 5th ribs. Benign bone disease of the auricular surface of the right iliac bone, please follow up.

6. Uneven thyroid density, increased FDG metabolism, please use ultrasound and laboratory tests.

7. No obvious abnormalities were found on cranial scintigraphy. Reactive hyperplasia of bilateral cervical lymph nodes was observed.

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.
