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: A few punctate low-density shadows were observed in the deep bilateral cerebral regions; no abnormal density shadows were seen in the remaining brain parenchyma.
FDG uptake was normal.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no obvious abnormalities.
No thickening was observed in the paranasal sinus mucosa; the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; FDG uptake was normal.
The pharyngeal recesses were symmetrical bilaterally; there was no stenosis of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the bilateral parapharyngeal spaces were clear, and FDG uptake was normal.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
The thyroid gland is normal in shape and size, with uneven density, and elevated FDG metabolism (SUVmax = 3.2).
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
An irregular mass, approximately 3.0 2.5 cm in size, was seen in the anterior segment of the right upper lobe, with lobulated and spiculated margins, and elevated FDG metabolism (SUVmax = 8.5).
A mixed ground-glass opacity, approximately 0.9 0.6 cm in size, was seen in the apical segment of the right upper lobe, with slightly elevated FDG metabolism (SUVmax = 1.5).
Calcification was observed in the posterior segment of the left upper lobe.
Several solid micronodules, approximately 0.2?.4 cm in long diameter, with clear borders, were seen in both lungs; no abnormalities were observed in FDG metabolism.
A few patchy, speckled, and linear lesions were also seen in both lungs, more prominent in the right upper lobe, with no abnormalities in FDG metabolism.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
Multiple enlarged lymph nodes were observed in the right hilum, pretracheal space, and aortic window, the largest measuring approximately 3.3 cm in short diameter, with increased FDG metabolism (SUVmax = 10.6).
The cardiac silhouette was normal.
The esophagus showed no dilation, no significant thickening or mass in the wall, and no increased FDG uptake.
Gastric distension was poor, with no significant thickening of the gastric wall and no significant abnormalities in FDG uptake.
Intestinal distension was poor, with increased FDG metabolism in some intestinal segments (SUVmax = 4.8).
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure; a cystic lesion approximately 1.1 cm in long diameter was observed in the right lobe of the liver, with absent FDG uptake.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size, with no thickening of the gallbladder wall and no abnormalities in localized FDG uptake.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is not significantly abnormal.
The spleen is normal in shape, size, density, and FDG uptake.
A cystic lesion is seen in the left kidney, with a long diameter of approximately 2.4 cm, and FDG uptake is absent.
The right kidney is normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureter are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland contrast is normal.
The prostate is full in shape, with a transverse diameter of approximately 5.0 cm, and punctate calcifications are seen inside.
No abnormal FDG metabolism is observed.
The bladder is generally full, and no obvious positive stones are seen inside.
No enlarged lymph nodes are seen in the abdomen, pelvis, or retroperitoneal region.
No significant fluid accumulation is seen in the abdomen or pelvis.
Bilateral inguinal canals are dilated.
Scoliosis, sacralization of the lumbar spine, instability of the L2 and L4 vertebral bodies, calcification of the nuchal ligament, and endplate inflammation of the L3/4 vertebral bodies.
L4/5 disc bulge, L5/S1 disc herniation.
Systemic bone marrow FDG metabolism was normal.

Impression

1. a. A mass in the anterior segment of the right upper lobe, with increased FDG metabolism, suggestive of lung cancer. Multiple lymph node metastases in the right hilum and mediastinum. b. A mixed ground-glass opacity in the apical segment of the right upper lobe, with mildly increased FDG metabolism, suggestive of atypical adenomatous hyperplasia. Early lung cancer needs to be ruled out. Further comparison with older CT scans is recommended, and clinicopathological examination may be necessary.

2. Several solid micronodules of chronic inflammation in both lungs. Calcification in the posterior segment of the left upper lobe. A few scattered chronic inflammatory and old lesions in both lungs.

3. A few ischemic lesions in the deep bilateral brain regions; MRI is recommended.

4. Liver cyst. Left kidney cyst. Benign prostatic hyperplasia with calcifications. Bilateral inguinal canal dilation.

5. Increased FDG metabolism in parts of the intestine, likely due to inflammatory uptake; colonoscopy is recommended.

6. Scoliosis with degenerative changes, sacralization into lumbar spine, instability of L2 and L4 vertebral bodies. L3/4 vertebral endplate inflammation. L4/5 intervertebral disc bulge, L5/S1 intervertebral disc herniation.

7. Uneven thyroid density, increased FDG metabolism, suggesting a high probability of inflammatory changes; ultrasound and thyroid function tests are 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.
