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 few punctate low-density shadows were seen in the deep bilateral cerebral regions; no abnormal density shadows were seen in the remaining brain parenchyma, and FDG uptake was normal.
The ventricles, sulci, fissures, and cisterns were widened; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no obvious abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening, and FDG uptake was normal.
The pharyngeal recesses were symmetrical bilaterally, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were normal, and the bilateral parapharyngeal spaces were clear, with no abnormal FDG uptake.
A soft tissue nodule was seen in the left palatine tonsil, with a long diameter of approximately 1.0 cm, showing increased FDG metabolism (SUVmax = 7.4).
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
No abnormalities were observed in the morphology and structure of the laryngopharynx.
A low-density nodule, approximately 0.4 cm in long diameter, was found in the right lobe of the thyroid gland; FDG metabolism was normal.
The left lobe showed uniform density, and FDG uptake was normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
An irregular nodule, approximately 2.5 1.6 cm in size, with lobulated margins, was found near the hilum in the right upper lobe of the lung; FDG metabolism was increased (SUVmax = 28.5).
Adjacent bronchus was obstructed.
Patchy consolidation and patchy hazy shadows were observed around the lesion; FDG metabolism was increased (SUVmax = 3.6).
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
Multiple lymph nodes were observed in the right hilum, pretracheal space, para-aortic arch, aortopulmonary window, and subcarinal region; the largest had a short diameter of approximately 0.9 cm; FDG metabolism was increased (SUVmax = 5.9).
No abnormalities were observed in the cardiac silhouette.
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure; patchy calcifications were observed in the right posterior lobe of the liver, but FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size, no thickening of the gallbladder wall, and no abnormalities in localized FDG uptake.
The pancreatic head showed slightly decreased density and increased FDG metabolism (SUVmax = 2.6); the main pancreatic duct was slightly widened, but FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
A cystic lesion was seen in each kidney, the largest being approximately 2.4 cm in length, with no FDG uptake.
A fat-density shadow was seen at the outer edge of the left kidney, approximately 0.4 cm in length, with a CT value of approximately -11 HU, and no FDG uptake.
No widening of the renal pelvis, calyces, or ureter was observed, and no significant abnormalities in FDG uptake were seen.
No significant abnormalities were seen in bilateral adrenal glands.
Gastric distension was poor, with slight thickening of the walls in parts of the gastric body and antrum, and mildly increased FDG uptake (SUVmax = 2.3).
Intestinal distension was unsatisfactory, with continuous increased FDG uptake in parts of the colon and rectum (SUVmax = 4.5).
An air-filled cavity was seen in the descending duodenum, with no abnormalities in FDG uptake.
The prostate was full in shape, approximately 5.0 cm in diameter, with punctate calcifications inside, and increased FDG uptake (SUVmax = 3.2).
Bladder distension was normal, with no obvious positive stones seen.
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.
Systemic bone marrow FDG metabolism was normal.

Impression

1. a. A mass near the hilum in the right upper lobe of the lung, with increased FDG metabolism, suggestive of central lung cancer with surrounding obstructive inflammation, and partial carcinomatous lymphangitis in the right upper lobe. b. Right hilar lymph node metastasis; possible reactive hyperplasia of mediastinal lymph nodes, follow-up recommended to rule out metastasis. c. A few ischemic lesions in the deep bilateral brain; age-related encephalopathy.

2. Slightly decreased density in the pancreatic head, mildly increased FDG metabolism, and slightly widened main pancreatic duct, suggesting possible inflammatory uptake; enhanced MRI recommended to rule out tumor. Liver calcifications.

3. Soft tissue nodule in the left palatine tonsil, with increased FDG metabolism, suggesting inflammation; tumor to be ruled out, clinical specialist examination recommended.

4. Bilateral renal cysts. Left renal angiomyolipoma.

5. Slight thickening of the walls of part of the gastric body and antrum, with mildly increased FDG uptake, suggestive of chronic gastritis; continuous increased FDG metabolism in part of the colon and rectum, suggestive of inflammatory or physiological uptake; duodenal diverticulum.

6. Benign prostatic hyperplasia with calcification, increased FDG metabolism in the gland, suggestive of inflammatory or physiological uptake; follow-up PSA and ultrasound examination recommended.

7. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulge.

8. Low-density nodule in the right lobe of the thyroid gland, no abnormalities in FDG metabolism, suggestive of adenoma; ultrasound examination recommended.

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.
