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 lesions in the deep bilateral cerebral regions; no significant abnormalities in FDG metabolism.
Enlargement of the ventricles, sulci, fissures, and cisterns; symmetrical bilateral ventricles; no midline shift.
Normal bilateral eyeball morphology and contour; clear retrobulbar structures; symmetrical bilateral optic nerves; no abnormal FDG metabolism.
No thickening of the paranasal sinus mucosa; intact sinus walls.
No thickening of the nasopharyngeal wall; no stenosis of the bilateral pharyngeal recesses and Eustachian tube openings; normal structures of the infratemporal fossa and pterygopalatine fossa; clear bilateral parapharyngeal spaces; no abnormal FDG metabolism.
Physiological FDG metabolism in the oropharynx and laryngopharynx.
No abnormal contrast enhancement of the right parotid gland and bilateral submandibular glands.
Poor pneumatization of the bilateral mastoid processes.
The thyroid gland is normal in shape and size, with uniform density, and no abnormalities were observed in FDG metabolism.
A soft tissue nodule measuring approximately 1.0 0.9 cm is seen in the deep lobe of the left parotid gland, with increased FDG metabolism (SUVmax = 4.8).
A right supraclavicular fossa lymph node is visible, with a short diameter of approximately 1.1 cm, and increased FDG metabolism (SUVmax = 4.8).
An irregular soft tissue density mass is seen near the right hilum at the bronchial opening in the right lower lobe of the lung, with indistinct borders, a cross-sectional size of approximately 5.6 4.3 cm, increased FDG metabolism (SUVmax = 8.4), surrounding adjacent blood vessels, with distal consolidation and atelectasis, and slightly increased FDG metabolism (SUVmax = 2.5).
Several small solid nodules are present in both lungs, with regular shape, clear borders, and a long diameter of approximately 0.2?.5 cm; no abnormalities were observed in FDG uptake.
A few linear lesions and calcifications were observed in both lungs, with no abnormalities in FDG metabolism.
Small cystic lucent shadows were seen in the subpleural region of both upper lobes.
Right-sided pleural effusion was present.
Lymph nodes in the right hilum and mediastinum (right upper mediastinal entrance, pretracheal vena cava, subcarinal, prepericardial space, and right posterior space) were visible, some of which were fused, with the largest measuring approximately 5.1*4.1cm in cross-section.
FDG metabolism was increased, with SUVmax=7.3.
The cardiac silhouette was normal.
Calcification of some arterial walls was observed (including the coronary arteries).
The liver morphology and size were normal, with smooth liver margins and no widening of the hepatic fissure.
CT scan revealed multiple slightly low-density nodules in the liver parenchyma with indistinct borders, the largest measuring approximately 1.8*1.4cm in cross-section.
FDG metabolism was increased, with SUVmax=3.7.
The main portal vein was not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder is normal in shape and size, with no thickening of the gallbladder wall and no abnormalities in local FDG metabolism.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG metabolism.
The spleen is normal in shape, size, density, and FDG metabolism.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG metabolism is not significantly abnormal.
A round, isodense nodule with a long diameter of approximately 1.3 cm is seen in the left adrenal gland, with clear borders and increased FDG metabolism (SUVmax = 4.1); the right adrenal junction is slightly thickened, with slightly increased FDG metabolism (SUVmax = 2.1).
The esophagus is not dilated, with no obvious thickening or mass in the esophageal wall, and no increased FDG metabolism.
The stomach is generally full, with no obvious thickening of the stomach wall, and no obvious abnormalities in FDG metabolism.
The intestines are poorly full, with increased FDG metabolism in parts of the colon and rectum (SUVmax = 4.6).
The prostate is normal in shape and size, with no obvious abnormal density shadows in the parenchyma, and no abnormal FDG metabolism.
The bladder is poorly full, with no obvious positive stones.
Fluid density shadows are present in both scrotums, but FDG metabolism is absent.
A lymph node with a short diameter of approximately 1.1 cm is seen below the head of the pancreas, with increased FDG metabolism (SUVmax = 4.3).
No obvious fluid accumulation is seen in the abdomen or pelvis.
The spinal alignment is normal, with some vertebral body margin osteophytes.
The sacral canal is dilated, containing a cystic lesion measuring approximately 4.0*3.4 cm, and L4/5 and L5/S1 intervertebral disc bulges, with no abnormalities in FDG metabolism.
Increased FDG metabolism in the T2 spinous process, T12 vertebral body, left and right pubic tubercle of the sacrum, SUVmax=2.9.

Impression

1. a. A mass near the right hilum at the bronchial opening in the right lower lobe, encircling adjacent blood vessels, with increased FDG metabolism, suggestive of central lung cancer with obstructive inflammation. Right-sided pleural effusion. b. Lymph node metastases in the right hilum, mediastinum, right supraclavicular fossa, and below the pancreatic head. c. Multiple liver metastases. A left adrenal metastasis is highly probable. Bone metastases in the T2 spinous process, T12 vertebral body, left sacrum, and right pubic tubercle. d. Several small, solid, chronic inflammatory nodules in both lungs; please follow up with CT scans. A few post-inflammatory remnants and calcifications in both lungs. Paraseptal emphysema in both upper lobes. Partial arteriosclerosis (including coronary arteries).

2. Right adrenal hyperplasia. Bilateral hydrocele.

3. Increased FDG metabolism in parts of the colon and rectum, possibly due to physiological uptake or chronic inflammation; please follow up with endoscopy.

4. Degenerative changes in the spine. Sacral canal cyst, L4/5 and L5/S1 disc bulge.

5. Age-related brain changes; MRI recommended. Deep lacunar infarcts.

6. Bilateral mastoid hypopneumatization. Likely a mixed tumor or adenolymphoma in the deep lobe of the left parotid gland; ultrasound follow-up 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.
