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.
Widening 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.
Slight thickening of the mucosa in the right maxillary sinus; intact sinus wall; absent FDG metabolism.
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 bilateral parotid and submandibular glands.
The thyroid gland is normal in shape and size, with uneven density and unevenly increased FDG metabolism (SUVmax = 3.8).
No obviously enlarged lymph nodes were seen in the bilateral deep cervical spaces, submandibular region, or submental region.
An irregularly lobulated soft tissue density mass was seen in the apical-posterior segment of the left upper lobe, with relatively clear borders, measuring approximately 3.9*2.7*2.4cm in cross-section.
FDG metabolism was increased (SUVmax = 20.5), with surrounding long spiculations and local pleural traction.
Several small solid nodules were found in the apical-posterior segment and superior lingular segment of the left upper lobe, the posterior segment of the left lower lobe, the apical segment of the right upper lobe, and the posterior basal segment of the right lower lobe.
These nodules were regular in shape, with clear borders, and a long diameter of approximately 0.2-0.4cm.
FDG uptake was normal.
Subpleural calcification was found in the apical-posterior segment of the left upper lobe.
A few linear and flocculent density shadows were also seen in both lungs, with no abnormal FDG metabolism.
Small cystic lucent shadows were seen in both lungs.
Slight thickening of the pleura was observed bilaterally, but there was no pleural effusion or pneumothorax.
Hilar and mediastinal lymph nodes (pretracheal, post-vena cava, aortic window, parapulmonary arch, and subcarinal) were visualized, the largest measuring approximately 1.1 cm in short diameter, with increased FDG metabolism (SUVmax = 9.5).
The cardiac silhouette was normal.
Some arterial walls showed calcification.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Plain CT scan revealed several low-density nodules within the liver parenchyma, with smooth edges; the largest measuring approximately 0.5 cm in long diameter, and lacking FDG metabolism.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts.
The gallbladder was absent post-operatively.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma; the main pancreatic duct was not widened, and FDG metabolism was normal.
Spleen morphology, size, density, and FDG metabolism were normal.
Several cystic low-density lesions were seen in the left kidney and left renal pelvis, with clear borders; the largest was approximately 6.4 cm in long diameter, and FDG metabolism was absent.
The right kidney was normal in shape and size, and no obvious abnormal density shadows were seen in the parenchyma.
No widening was seen in the right renal pelvis, calyces, or ureter, and no obvious abnormalities were seen in FDG metabolism.
No obvious abnormalities were seen on bilateral adrenal gland imaging.
No esophageal dilation was seen, and no obvious thickening or mass was seen in the esophageal wall; FDG metabolism was not increased.
The stomach was poorly filled, with slight thickening of the antral wall; FDG metabolism was increased, SUVmax=3.1.
The intestine was poorly filled, with no obvious thickening or mass in the intestinal wall; FDG metabolism was physiological.
The prostate was enlarged, and the parenchymal FDG metabolism was uneven, SUVmax=4.8.
The bladder was poorly filled, and no obvious positive stones were seen within it.
No enlarged lymph nodes were observed in the abdomen, pelvis, or retroperitoneal region.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with calcification of the nuchal ligament and osteophyte formation at the margins of some vertebral bodies.
L4/5 and L5/S1 intervertebral disc bulges were observed, but FDG metabolism was normal.
FDG metabolism was increased around the right shoulder joint, with SUVmax = 4.8.

Impression

1. a. A mass in the posterior segment of the left upper lobe, with increased FDG metabolism, suggestive of peripheral lung cancer. Metastasis to the hilar and mediastinal lymph nodes is highly probable. Please correlate with clinicopathology. b. Scattered chronic inflammatory nodules (solid and calcified) in both lungs. Please correlate with CT follow-up. A few post-inflammatory lesions in both lungs. Emphysema in both lungs. Mild pleural thickening bilaterally. Partial arteriosclerosis.

2. Benign prostatic hyperplasia, with uneven FDG metabolism, suggestive of inflammatory or physiological uptake. PSA and ultrasound follow-up are recommended. A biopsy may be necessary.

3. Uneven thyroid density, with unevenly increased FDG metabolism, suggestive of thyroiditis. Please correlate with ultrasound and thyroid function tests.

4. Small liver cysts. Absence after gallbladder surgery. Cysts in the left kidney and left renal pelvis.

5. Chronic antral gastritis.

6. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulge. Right-sided frozen shoulder.

7. Age-related brain changes, deep lacunar infarcts in the brain; MRI recommended. Minor 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.
