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: Brain morphology and structure were normal, with punctate, slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
The ventricles, sulci, fissures, and cisterns were widened, but local density and FDG uptake were normal; midline shift was not observed.
Both eyes were symmetrical, with no obvious abnormalities.
The right maxillary sinus mucosa was thickened, with multiple cystic shadows in both maxillary sinuses; the remaining paranasal sinuses showed no thickening, and the sinus walls were intact.
The nasal septum was deviated; the nasopharyngeal wall was not thickened, and FDG uptake was normal.
The pharyngeal recesses were symmetrical, 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.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The oropharynx and laryngopharynx showed no abnormalities in morphology and structure.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
The lung markings are disordered.
An irregular soft tissue nodule is seen in the posterior segment of the right upper lobe, with clear borders, lobulated and spiculated edges, and slightly uneven density, measuring approximately 2.2*1.6*1.8cm.
FDG uptake is increased, SUVmax=8.8, and stenosis is visible in the adjacent bronchus.
Multiple solid nodules and plaque-like lesions are also seen in both lungs, with clear borders.
The largest is located in the apical segment of the right upper lobe, with a long diameter of approximately 1.2cm.
FDG uptake is normal.
Increased lung translucency is observed in both lungs, with scattered calcifications and linear lesions; FDG uptake is normal.
Right pleural thickening is present, but there is no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette is normal.
The cardiac chamber density is slightly lower than that of the myocardium, and some arterial walls are calcified (including the coronary arteries).
The esophagus is not dilated, and the wall is not significantly thickened or swollen; FDG uptake is not increased.
The liver is normal in shape and size, with smooth borders and no widening of the hepatic fissure.
Dense nodules are present at the top of the diaphragm, the largest being approximately 0.5 cm in diameter; FDG uptake is normal.
The main portal vein is not significantly widened, and intrahepatic and extrahepatic bile ducts are not dilated.
The gallbladder is normal in shape and size, with a thickened wall and several dense nodules within, the largest approximately 2.0 cm in diameter; local FDG uptake is normal.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma; the main pancreatic duct is not widened; FDG uptake is normal.
The spleen is absent.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging shows no obvious abnormalities.
The stomach is adequately filled, with a considerable amount of residual contents and slight thickening of the stomach wall.
FDG uptake is slightly increased, with SUVmax=3.1.
The intestines are not sufficiently filled, with a considerable amount of residual contents, and the intestinal uptake is physiological.
The prostate is full, with punctate dense shadows seen within it; FDG uptake is not abnormally increased.
The bladder is poorly filled, with no obvious positive stones seen.
No enlarged lymph nodes were seen in the abdomen or pelvis.
No obvious fluid accumulation was seen in the abdominal or pelvic cavities.
A cystic low-density lesion was observed in the right inguinal region, with a cross-sectional area of approximately 3.9*2.2cm; FDG uptake was not abnormal.
Decreased bone density throughout the body, normal spinal alignment, osteophyte formation at the margins of some vertebral bodies, flattening of the L3 vertebral body with a well-defined low-density lesion surrounded by sclerosis, measuring approximately 2.1*1.9cm; FDG metabolism was normal.
L4/5 and L5/S1 intervertebral disc bulges.
Calcification foci in the soft tissue surrounding the right iliac crest.
Whole-body bone marrow FDG metabolism was normal.

Impression

1. a. Irregular soft tissue nodules with increased FDG metabolism in the posterior segment of the right upper lobe, suggestive of peripheral lung cancer; please correlate with clinicopathology. b. Chronic inflammatory nodules in the remaining two lungs; follow-up CT scan recommended. Emphysema in both lungs; scattered post-inflammatory lesions in both lungs. Right pleural thickening. Mild anemia; partial arterial wall calcification (including coronary arteries).

2. Liver calcifications. Chronic cholecystitis; gallstones. Postoperative changes in the spleen.

3. Cystic mass in the right inguinal region, suggestive of benign; ultrasound follow-up recommended. Benign prostatic hyperplasia with calcification.

4. Partial chronic inflammatory changes in the gastric wall; please correlate with endoscopy.

5. Osteoporosis; degenerative changes in the spine; L4/5 and L5/S1 intervertebral disc bulges. L3 vertebral body wedge deformity, benign osteopathy of the L3 vertebral body. Calcifications in the soft tissue around the right iliac crest.

6. Senile brain, deep lacunar infarcts. Bilateral maxillary sinus submucosal cysts, 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.
