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.
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 structurally normal, and the bilateral parapharyngeal spaces were clear with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx showed no abnormalities in morphology or structure.
The thyroid gland is enlarged with uneven density; FDG uptake is normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
An irregular mass measuring approximately 4.94.85.5cm was observed in the posterior segment of the right lower lobe; FDG metabolism was increased (SUVmax=9.4), with patchy areas of increased density distally.
Several small solid nodules, approximately 0.2-0.4cm in long diameter, with clear borders, were observed in both lungs; FDG metabolism was normal.
Bronchiectasis was present in parts of both lungs, with scattered patchy shadows and linear lesions; FDG metabolism was normal.
The pleura was slightly thickened bilaterally, with a small to moderate amount of pleural effusion in the right pleural cavity.
Multiple slightly enlarged lymph nodes were observed in the bilateral hilar regions, pretracheal spaces, para-aortic arch, aortopulmonary window, and subcarinal region; the largest had a short diameter of approximately 1.1cm; FDG metabolism was increased (SUVmax=3.0).
Cardiac imaging was normal.
Calcification was observed in some arterial walls (including the coronary arteries).
The esophagus showed no dilation, no significant thickening or mass in the wall, and no increased FDG uptake.
The liver's shape and size were normal; the liver margins were smooth, the hepatic fissures were not widened, and punctate calcifications were observed within the liver; 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 was absent post-operatively.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma; the main pancreatic duct was not widened, and FDG uptake was normal.
The spleen's shape, size, density, and FDG uptake were normal.
A cystic lesion was observed in each kidney, the larger one approximately 3.7 cm in long diameter, located in the right kidney; FDG uptake was absent, and no widening was observed in the renal pelvis, calyces, or ureter; FDG uptake was normal.
Bilateral adrenal gland imaging showed no obvious abnormalities.
Stomach distension was poor, with no obvious thickening of the gastric wall, and no obvious abnormalities in FDG uptake.
Intestinal distension was poor, with no obvious thickening or mass in the intestinal wall, and FDG uptake was physiological.
The prostate was full in shape, with a transverse diameter of approximately 5.3 cm, containing several irregular punctate calcifications, but no abnormal FDG metabolism was observed.
Bladder distension was normal, with no obvious positive stones.
No enlarged lymph nodes were seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No obvious fluid accumulation was seen in the abdominal or pelvic cavities.
The right inguinal canal was dilated, but FDG metabolism was normal.
The L2 and L3 vertebral bodies showed mild posterior displacement, with some vertebral body margin osteophyte formation, and L4/5 and L5/S1 intervertebral disc bulging.
Systemic bone marrow FDG metabolism was normal.

Impression

1. a. A mass in the posterior segment of the right lower lobe, with increased FDG metabolism, suggestive of lung cancer with obstructive changes; please correlate with clinicopathology. b. Small to moderate pleural effusion on the right side. Slight pleural thickening bilaterally. Possible reactive hyperplasia of hilar and mediastinal lymph nodes, with partial metastasis to be ruled out; follow-up is recommended. c. Several small, solid, chronic inflammatory nodules in both lungs. Partial bronchiectasis in both lungs. Scattered chronic inflammation and old lesions in both lungs. Calcification of some arterial walls (including coronary arteries).

2. Calcification in the liver. Bilateral renal cysts. Benign prostatic hyperplasia with calcification. Enlargement of the right inguinal canal.

3. Mild posterior slippage of the L2 and L3 vertebral bodies. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulges.

4. A few ischemic lesions in the deep bilateral brain regions; age-related brain. Follow-up MRI is recommended.

5. Enlarged thyroid gland with uneven density; FDG uptake normal; nodular goiter suggested; 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.
