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

Under fasting conditions, an intravenous injection of 18F-FDG was administered, followed by rest.
Whole-body PET/CT imaging revealed: A few punctate low-density shadows were observed in the deep bilateral cerebral regions; FDG uptake showed no significant abnormalities.
The ventricles, sulci, fissures, and cisterns were widened; the ventricles were symmetrical, and midline shift was normal.
The eyeballs were symmetrical bilaterally, with no significant abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening; FDG uptake was normal.
The pharyngeal recesses were symmetrical bilaterally, 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.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx showed no abnormalities in morphology or structure.
A low-density nodule measuring approximately 1.1 0.8 cm is observed in the left lobe of the thyroid gland, with increased FDG metabolism (SUVmax = 3.6).
The right lobe of the thyroid gland shows uniform density, with no abnormal FDG uptake.
No enlarged lymph nodes are seen in the bilateral deep cervical spaces or submandibular region.
An irregular mass measuring approximately 4.2 3.7 cm is seen in the left upper lobe of the lung, with lobulated and spiculated margins, increased FDG metabolism (SUVmax = 16.3), and stenosis or occlusion of the apical and anterior segments of the left upper lobe bronchus.
Increased translucency is observed in both lungs, with a few speckled and linear opacities, but no abnormal FDG uptake.
No pleural thickening is observed bilaterally, and there is no pleural effusion or pneumothorax bilaterally.
Multiple enlarged lymph nodes are seen in the left hilum, para-aortic arch, and aortopulmonary window, the largest with a short diameter of approximately 1.5 cm, showing increased FDG metabolism (SUVmax = 9.5).
No abnormalities are observed in the cardiac silhouette.
Partial calcification of the arterial wall.
No esophageal dilation, wall thickening, or mass was observed; FDG uptake was not increased.
The liver showed no significant abnormalities in shape or size; the liver margins were smooth, and the hepatic fissures were not widened.
Several cystic lesions were observed within the liver, the largest with a long diameter of approximately 1.2 cm; FDG uptake was absent.
The main portal vein showed no significant widening; no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder was absent post-operatively.
The pancreas was normal in shape, with several punctate calcifications; the main pancreatic duct was not widened; FDG uptake was not significantly abnormal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size; a cystic low-density lesion with a long diameter of approximately 1.2 cm was observed in the left kidney; FDG uptake was not abnormal.
The renal pelvis, calyces, and ureter showed no widening; FDG uptake was not significantly abnormal.
Bilateral adrenal gland imaging showed no obvious abnormalities.
Stomach distension was poor, with no obvious thickening of the gastric wall and no obvious abnormalities in FDG uptake.
Intestinal distension was poor, with segmental FDG metabolism increased in some colorectal segments (SUVmax = 5.9).
Increased density was observed in the appendix lumen.
The prostate was slightly full in shape, with uniform density, and no abnormal FDG metabolism was observed.
Bladder distension was normal, with no obvious positive stones.
No enlarged lymph nodes were observed in the abdominal cavity, pelvis, or retroperitoneal region.
No obvious fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulges.
Localized bone destruction was observed in the left 8th rib, with sclerosis at the margins and increased FDG metabolism (SUVmax = 5.6).
A patchy, dense shadow was observed in the left acetabulum, with a long axis of approximately 1.1 cm.
FDG metabolism was normal.

Impression

1. a. Mass in the left upper lobe of the lung, with increased FDG metabolism, suggestive of lung cancer. Multiple lymph node metastases in the left hilum and mediastinum. b. Localized bone destruction in the left 8th rib, with sclerosis at the margins, increased FDG metabolism, metastasis to be ruled out; please correlate with clinical findings and closely monitor. c. Emphysema in both lungs. Minor chronic inflammation and remnants in both lungs. Calcification of some arterial walls.

2. Low-density nodule in the left lobe of the thyroid gland, with increased FDG metabolism, suggestive of an adenomatous nodule; ultrasound examination is recommended, and fine-needle aspiration biopsy may be necessary to rule out malignancy.

3. Liver cyst. Pancreatic calcification. Left renal cyst. Benign prostatic hyperplasia.

4. Segmental increased FDG metabolism in part of the colorectal region, suggestive of inflammatory or physiological uptake. Appendicitis fecalith.

5. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulge. Left acetabular island.

6. A few ischemic lesions in the deep bilateral brain regions, indicative of age-related brain changes.

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.
