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: Normal brain morphology and structure, with patchy, slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
Widening of the ventricles, sulci, fissures, and cisterns was observed, but local density and FDG uptake were normal; midline shift was not observed.
Bilateral eyeballs were symmetrical with no obvious abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; the palatine tonsils were symmetrical, and FDG uptake was physiological.
The laryngopharynx was normal in morphology and structure.
Bilateral parotid and submandibular glands showed normal morphology and density, with physiological FDG uptake.
The thyroid gland was normal in morphology and size, with uniform density; FDG uptake was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region.
Following lung cancer treatment, a patchy soft tissue density shadow measuring approximately 7.6 x 5.0 cm was observed in the right lower lobe, with increased FDG uptake (SUVmax = 19.0).
A bronchus was seen penetrating within the shadow, indicating bronchial occlusion in the posterior segment of the right lower lobe.
The lesion invaded the adjacent pleura, showing multiple nodular thickenings of the right pleura with increased FDG uptake (SUVmax = 4.2).
A small amount of pleural effusion was present on the right side.
Several small solid nodules were observed in both lungs, the largest being located in the posterior segment of the left upper lobe, with a long diameter of approximately 0.5 cm.
No abnormal FDG uptake was observed in these nodules.
Patchy shadows were also observed in the apical segment of the right upper lobe, with no abnormal FDG metabolism.
Scattered linear lesions were present in both lungs, with no abnormal FDG uptake.
Enlarged lymph nodes were visible in the right hilum and below the carina, some with indistinct borders with the right lower lobe lesion.
The largest lymph node had a short diameter of approximately 1.8 cm and increased FDG uptake (SUVmax = 13.9).
The cardiac silhouette appeared normal, with pericardial thickening and a small amount of effusion.
Arteriosclerosis was observed, and linear dense shadows were seen along the coronary artery course.
A port-a-cath was inserted in the right clavicular region.
The esophagus showed no dilation, 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 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 dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape or size, and the wall was not thickened; local FDG uptake was normal.
Calcification of the spleen capsule was observed, but FDG uptake was normal.
A soft tissue density mass measuring approximately 3.0*2.3cm was seen in the pancreatic tail region, with increased FDG uptake (SUVmax = 16.3).
The pancreatic duct was not dilated, the pancreatic head showed decreased density, and the remaining pancreas showed no abnormal density shadows.
A small nodule, approximately 0.8 cm in diameter, was observed adjacent to the mass, showing increased FDG uptake (SUVmax = 8.0).
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters were not widened, and FDG uptake was not significantly abnormal.
Bilateral adrenal gland imaging showed no obvious abnormalities.
Postoperative gastric cardia cancer surgery resulted in the absence of the stomach; no thickening was observed around the anastomosis wall, and FDG metabolism was normal.
Intestinal distension was unsatisfactory; no mass was observed locally, but there was considerable contents and residual gas in the intestinal lumen.
FDG uptake was continuously increased in some intestinal segments (SUVmax = 11.8).
The prostate was of normal size and homogeneous density, with no abnormally increased FDG uptake.
The bladder was poorly distended, containing high-density shadows.
Overall bone density was decreased; the spinal alignment was normal, with osteophyte formation at the margins of some vertebral bodies, multiple lumbar disc bulges, flattening of the L3 vertebral body, and decreased FDG metabolism in some cervical and thoracic vertebrae.

Impression

  1. a. After lung cancer treatment, a mass in the lower lobe of the right lung with increased FDG metabolism suggests continued high tumor activity. Right hilar and mediastinal lymph node metastasis. Right pleural metastasis, small amount of right pleural effusion. b. Patchy lesion in the apical segment of the upper lobe of the right lung, FDG metabolism normal; comparison with previous imaging data and follow-up are recommended. c. Bilateral chronic inflammatory nodules are highly probable; comparison with old images and re-examination are recommended. Scattered post-inflammatory lesions in both lungs. d. Pericardial thickening with a small amount of effusion, arteriosclerosis, changes after coronary stent placement. Right clavicular port placement.

  2. Mass in the pancreatic tail region with increased FDG metabolism, suggestive of metastasis; please combine with MRI.

  3. Postoperative changes in gastric cardia cancer; no signs of tumor recurrence in the surgical area; please combine with gastroscopy for follow-up.

  4. Splenic capsule calcification. Residual contrast agent in the cystostomy.

  5. Possible chronic inflammatory changes in some intestinal segments; please combine with endoscopy for follow-up.

  6. Osteoporosis, degenerative changes in the spine, multiple lumbar disc bulges, and wedge-shaped deformity of the L3 vertebral body. Some changes are post-radiotherapy changes in the cervical and thoracic spine.

  7. Elderly brain, deep lacunar infarcts and softening lesions in the brain; MRI follow-up is 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.
