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; there was no midline shift.
Both eyes were symmetrical, with no obvious abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening, 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; FDG uptake was normal.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The oropharynx and laryngopharynx showed no abnormalities in morphology and structure.
The thyroid gland was normal in shape and size, with slightly uneven density; FDG uptake was normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
An irregular mass with indistinct borders was observed in the left upper lobe, containing multiple cavities, measuring approximately 11.0*6.2*11.3cm.
FDG uptake was unevenly increased, with SUVmax=16.6.
A bronchus in the left upper lobe was truncated.
Multiple patchy shadows with increased FDG uptake were observed in the left upper lobe, with SUVmax=13.2.
Adjacent pleural thickening was also observed.
Multiple solid nodules with clear borders were observed in both lungs, the largest being approximately 0.5cm in diameter.
No abnormal FDG uptake was observed.
Scattered calcifications and linear lesions were observed in both lungs, with no abnormal FDG uptake.
Multiple enlarged lymph nodes were observed in the bilateral hilar regions, pretracheal space, para-aortic arch, aortopulmonary window, subcarinal region, and paraesophageal region of the posterior mediastinum.
The largest, located subcarinal region, had a short diameter of approximately 1.3 cm.
FDG uptake was increased, with an SUVmax of 8.6.
The cardiac silhouette appeared normal, but pericardial thickening with a small amount of effusion was observed.
The cardiac chamber density was slightly lower than myocardial density, and some arterial walls showed calcification (including the coronary arteries).
Bilateral breast fibroadenomas were dense, with punctate dense shadows observed in the right breast.
FDG metabolism was normal.
The esophagus was not dilated, and the esophageal wall showed no significant thickening or mass.
FDG uptake was not increased.
The liver showed no significant abnormalities in shape or size, with smooth liver margins, no widening of the hepatic fissure, and slightly decreased liver density.
A small cystic lesion, approximately 1.0 cm in diameter, was observed in the left medial lobe of the liver.
FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder appeared normal in shape and size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormal FDG uptake.
The spleen appeared normal in shape, size, and density, but with increased FDG uptake (SUVmax = 5.9).
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureters, and no obvious abnormal FDG uptake.
The left adrenal gland was slightly enlarged with increased FDG uptake (SUVmax = 3.2).
The right adrenal gland showed no obvious abnormalities on contrast.
Stomach distension is poor, with slight thickening of the walls of the cardia, part of the gastric body, and antrum.
FDG uptake is slightly increased, SUVmax=2.1.
Intestinal distension is unsatisfactory, with no obvious space-occupying lesions observed; intestinal uptake is physiological.
Uterus is small, with no abnormal density shadows observed.
Patchy FDG uptake in the uterine cavity is increased, SUVmax=3.0.
No obvious abnormalities were observed in the bilateral adnexa.
Bladder distension is poor, with no obvious positive stones observed.
No enlarged lymph nodes were observed in the abdomen or pelvis.
No obvious fluid accumulation was observed in the abdomen or pelvis.
Decreased bone density throughout the body, normal spinal alignment, with osteophyte formation at the margins of some vertebral bodies, and multiple intervertebral disc bulges with pneumoconiosis and degeneration.
No abnormalities were observed in FDG metabolism in the bone marrow.

Impression

1. a. A space-occupying lesion with cavity formation in the left upper lobe, with unevenly increased FDG metabolism, consistent with lung cancer, accompanied by obstructive inflammation in the left upper lobe; partial lymph node metastasis in both hilar and mediastinal regions. b. Chronic inflammatory nodules in both lungs; follow-up CT scan recommended. Scattered post-inflammatory lesions in both lungs. Pericardial thickening with a small amount of effusion, mild anemia, and partial calcification of arterial walls (including coronary arteries).

2. Bilateral breast hyperplasia, with calcification in the right breast.

3. Mild fatty liver, small cyst in the left lobe of the liver. Increased FDG metabolism in the spleen, suggestive of reactive hyperplasia.

4. Left adrenal hyperplasia. Possibly due to physiological uptake in the uterine cavity; follow-up ultrasound is recommended to rule out other possibilities.

5. Partial chronic inflammatory changes in the gastric wall; follow-up endoscopically recommended.

6. Osteoporosis, degenerative changes in the spine, multiple intervertebral disc bulges with pneumoconiosis.

7. Age-related brain abnormalities, deep lacunar infarcts.

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.
