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: Normal brain morphology and structure, with punctate low-density shadows in the deep cerebral regions bilaterally; FDG uptake was not significantly abnormal.
Some ventricles, sulci, fissures, and cisterns showed widening; local density and FDG uptake were normal, and midline shift was not observed.
The bilateral eyeballs showed normal morphology and contours; retrobulbar structures were clear; the bilateral optic nerves were symmetrical; FDG uptake was not significantly abnormal.
Mild thickening of the right maxillary sinus mucosa was observed; the sinus wall was intact.
No thickening of the nasopharyngeal wall was observed; FDG uptake was normal; the bilateral pharyngeal recesses were symmetrical; the Eustachian tube openings were not narrowed; the infratemporal fossa and pterygopalatine fossa structures were normal; the bilateral parapharyngeal spaces were clear; FDG uptake was normal.
The bilateral palatine tonsils were full; FDG uptake was physiological.
The laryngopharynx showed no abnormalities in morphology and structure.
No abnormal visualization of the bilateral salivary glands was observed.
The thyroid gland was normal in shape and size, with slightly uneven density; FDG uptake was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region, and FDG uptake was normal.
A soft tissue nodule was observed in the apical-posterior segment of the left upper lobe, with a maximum cross-section of approximately 2.5*1.8cm, irregular margins, pleural traction, and local bronchial truncation.
FDG uptake was increased, with SUVmax=17.5.
Patchy slightly high-density shadows were observed distal to the nodule.
Scattered nodules and plaque-like foci with a long diameter of approximately 0.3-0.5cm were observed in both lungs, with normal FDG uptake.
Scattered linear shadows and air-filled cavities were observed in both lungs, with some bullae forming.
Multiple lymph nodes were observed in the bilateral hilar regions, pretracheal vena cava, aortopulmonary window, para-aortic arch, and subcarinal region, with the largest having a short diameter of approximately 0.7cm.
FDG uptake was increased, particularly in the left hilar lymph nodes, with SUVmax=4.3.
Bilateral pleural nodular thickening with calcification (including interlobar pleura), no bilateral pleural effusion or pneumothorax.
Cardiac silhouette unremarkable.
Calcification of some arterial walls (including coronary arteries).
Esophageal dilatation not observed, no significant thickening or mass in the esophagus, no increased FDG uptake.
Liver morphology and size unremarkable, smooth liver margins, no widening of the hepatic fissure.
Calcification foci seen in the right lobe of the liver, no abnormal FDG uptake.
Main portal vein not significantly widened, no dilatation of intrahepatic or extrahepatic bile ducts.
Gallbladder morphology and size unremarkable, slightly rough gallbladder wall, nodular high-density shadows within the gallbladder, no abnormal FDG uptake.
Pancreas morphology unremarkable, no significant abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, no significant abnormal FDG uptake.
Spleen morphology and size unremarkable, density and FDG uptake unremarkable.
Bilateral renal malrotation, no significant abnormal density shadows in the renal parenchyma, no significant abnormal FDG uptake.
No widening of the renal pelvis, calyces, or ureters was observed bilaterally, and no positive stones were seen within them.
The bilateral adrenal glands showed no abnormalities in morphology or density, and FDG uptake was normal.
Gastric distension was poor, but FDG uptake was not significantly abnormal.
Bowel preparation was poor; no obvious masses were seen in the intestinal wall, but FDG uptake was increased in some intestinal segments (SUVmax = 6.6).
The prostate showed no abnormalities in morphology or size, with a transverse diameter of approximately 4.5 cm.
Calcifications were observed in the parenchyma, and localized increased FDG uptake was seen in the central zone (SUVmax = 6.0).
Bilateral hydrocele was present.
Bladder distension was poor, but no obvious positive stones were seen within it.
No enlarged lymph nodes were seen in the abdominal cavity, pelvis, or retroperitoneal region, and FDG uptake was normal.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes and L5/S1 intervertebral disc bulging.
Calcification was present in some areas of the anterior longitudinal ligament and nuchal ligament.

Impression

1. a. Soft tissue nodules in the apical-posterior segment of the left upper lobe, with increased FDG metabolism, suggestive of peripheral lung cancer. Please confirm the diagnosis with pathological examination. b. Left hilar lymph node metastasis to be ruled out; reactive hyperplasia of right hilar and mediastinal lymph nodes. Please follow up on the above. c. Chronic inflammatory nodules and plaque-like foci (solid) in both lungs. Bilateral pulmonary fibrosis, emphysema, bullae. Bilateral pleural nodular thickening with calcification. Partial arteriosclerosis (including coronary arteries).

2. Liver calcifications. Gallstones, chronic cholecystitis. Bilateral renal malrotation.

3. Prostatic calcifications, with localized high FDG metabolism in the central zone, suggesting possible urinary retention. Please rule out space-occupying lesions with PSA and MRI. Bilateral hydrocele.

4. Increased FDG metabolism in some intestinal segments, suggestive of physiological uptake or chronic inflammation. Please follow up with endoscopy.

5. Spinal degenerative changes. L5/S1 intervertebral disc bulge.

6. Bilateral deep lacunar infarcts, age-related brain abnormalities. Chronic inflammation of the right maxillary sinus.

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.
