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: patchy low-density lesions in the right cerebellum, with a maximum cross-sectional area of approximately 2.8 1.5 cm, with absent FDG uptake.
Patchy slightly low-density lesions were seen in the right frontal lobe, while the temporal lobe showed relatively uniform density; FDG metabolism was normal.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, with no obvious abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; FDG uptake was normal; the pharyngeal recesses were symmetrical; there was no stenosis of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear, and FDG uptake was normal.
Both palatine tonsils showed physiological uptake.
The morphology and structure of the laryngopharynx were normal.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
A solid mass with a large cystic cavity, measuring approximately 5.6 4.2 2.9 cm, is seen in the posterior segment of the right lower lobe; the solid portion shows increased FDG metabolism (SUVmax = 17.9).
Several small solid nodules, approximately 0.2-0.4 cm in long diameter, with clear borders, are seen in both lungs; FDG metabolism is normal.
Multiple scattered linear and punctate lesions are also seen in both lungs; FDG metabolism is normal.
Increased translucency of both lungs, with multiple air-filled cystic cavities.
The right pleura shows multiple nodular thickenings; FDG metabolism is slightly increased (SUVmax = 1.6).
The left pleura shows localized thickening; FDG uptake is normal.
Multiple enlarged lymph nodes are seen in the right hilum, superior mediastinal vascular space, pretracheal space, aortopulmonary window, subcarinal region, and right supraclavicular fossa; the largest has a short diameter of approximately 1.3 cm; FDG metabolism is increased (SUVmax = 29.1).
Cardiac imaging showed no abnormalities.
Calcification was observed in some arterial walls (including the coronary arteries).
The esophagus showed no dilation, wall thickening, or masses; FDG uptake was not increased.
The liver showed no significant abnormalities in shape or size; liver margins were smooth; the hepatic fissures were not widened; punctate dense shadows were observed in the right lobe of the liver; FDG uptake was not abnormal.
The main portal vein showed no significant widening; intrahepatic and extrahepatic bile ducts showed no dilation.
The gallbladder showed no abnormalities in shape or size; the gallbladder wall was not thickened; localized FDG uptake was not abnormal.
The pancreas was normal in shape; no significant abnormal density shadows were observed in the parenchyma; the main pancreatic duct was not widened; FDG uptake was not significantly abnormal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size; no significant abnormal density shadows were observed in the parenchyma; the renal pelvis, calyces, and ureters were not widened; FDG uptake was not significantly abnormal.
Bilateral adrenal gland imaging showed no significant abnormalities.
The stomach is poorly distended, with a protruding cystic cavity adjacent to the gastric fundus, connected to the gastric wall; FDG uptake is not significantly abnormal.
The intestines are poorly distended, with increased FDG metabolism in some intestinal segments (SUVmax = 3.5).
FDG metabolism at the anal orifice is increased (SUVmax = 8.9).
The prostate is full in shape, approximately 5.3 cm in diameter, with unevenly increased FDG metabolism (SUVmax = 2.6).
Punctate calcifications are seen in the left scrotum.
The bladder is generally full, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdominal cavity, retroperitoneum, or pelvic wall; FDG metabolism is normal.
No significant fluid accumulation is seen in the abdomen or pelvis.
The spinal alignment is normal, with some vertebral margin osteophytes and L4/5 and L5/S1 intervertebral disc bulges; FDG uptake is normal.
Multiple Schmorl's nodes are present in the thoracic and lumbar vertebrae.
A ring-shaped dense shadow is seen in the left iliac bone; FDG uptake is normal.
No abnormal FDG metabolism is observed in the entire skeletal system.

Impression

1. Right lung cancer after chemotherapy and brain metastasis after radiotherapy: a. Right lower lobe posterior segment lesion with increased FDG metabolism in the solid portion, suggesting tumor activity; multiple lymph node metastases in the right hilum, mediastinum, and right supraclavicular fossa; high probability of right pleural metastasis. b. After brain metastasis radiotherapy, patchy low-density shadow in the right cerebellum with lost FDG uptake; patchy slightly low-density lesions in the right frontal lobe, with relatively uniform density in the temporal lobe, and no abnormalities in FDG metabolism. Considering the changes after treatment, the tumor activity is likely to be basically suppressed; enhanced MRI follow-up is recommended. c. Several small chronic inflammatory nodules (solid) in both lungs. Scattered chronic inflammation and old lesions in both lungs. Emphysema with small bullae in both lungs. Calcification of some arterial walls (including coronary arteries). Localized thickening of the left pleura.

2. Diverticulum in the gastric fundus. Inflammatory or physiological uptake in some intestinal segments. Hemorrhoids.

3. Calcification in the right lobe of the liver. Benign prostatic hyperplasia, with uneven FDG metabolism in the gland; PSA and ultrasound follow-up are recommended. Left scrotal calcification.

4. Degenerative changes in the spine. Multiple Schmorl's nodes in the thoracic and lumbar vertebrae. L4/5 and L5/S1 intervertebral disc bulges. Benign osteopathy of the left iliac bone.

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.
