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 lesions in the deep brain regions; FDG metabolism was normal.
Patchy low-density lesions were seen in the left cerebellum, with absent FDG uptake.
The ventricles, sulci, fissures, and cisterns were widened, but local density and FDG uptake were normal; there was no midline shift.
The right lens was poorly visualized; no obvious abnormalities were seen in the left eye.
No thickening of the paranasal sinus mucosa was observed; the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; the palatine tonsils were symmetrical, and FDG uptake was physiological.
The laryngopharynx was normal in morphology and structure.
The parotid and submandibular glands were normal in morphology and density, with physiological FDG uptake.
The thyroid gland shows uneven density with several low-density nodules in both lobes, some with calcification.
The largest nodule is located in the right lobe, with a long diameter of approximately 1.0 cm.
FDG uptake is increased, with SUVmax=5.4.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region.
Following treatment for right lung cancer, an irregular soft tissue mass with indistinct borders, measuring approximately 9.0*8.0*8.7 cm, was observed in the right upper lobe.
Low-density necrotic areas were seen within the mass, with unevenly increased FDG uptake (SUVmax=12.0).
The mass invaded the adjacent pleura and the right second rib.
Multiple low-density nodules and masses of varying sizes were observed in the remaining lungs, some containing cavitation and calcification.
The largest nodule is located in the posterior segment of the left lower lobe, with a long diameter of approximately 4.6 cm.
FDG uptake is increased, with SUVmax=9.6.
Increased translucency of both lungs, multiple air-filled cavities, scattered patchy and linear lesions, and increased FDG uptake (SUVmax = 3.8).
Bilateral pleural thickening with a small amount of pleural effusion on the right side.
Lymph nodes are visualized in the pretracheal vena cava, aortopulmonary window, para-aortic arch, and subcarinal region; the largest has a short diameter of approximately 1.1 cm, with increased FDG uptake (SUVmax = 6.2).
Lymph nodes are visualized in the right hilum; the largest has a short diameter of approximately 0.8 cm, with increased FDG uptake (SUVmax = 4.6).
The cardiac silhouette appears normal, but pericardial thickening with effusion and a lower density in the cardiac chambers than in the heart chambers.
Calcification is present in some arterial walls (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 showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissure.
A low-density mass, approximately 3.3 cm in length, was observed under the capsule in the right posterior lobe of the liver, with increased FDG uptake (SUVmax = 10.5).
A cystic lesion, approximately 1.3 cm in length, was also observed in the right posterior lobe of the liver, with no abnormalities in FDG metabolism.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape and size, with no thickening of the gallbladder wall and no abnormalities in local FDG uptake.
The pancreas was normal in shape, with several punctate dense shadows observed within.
The main pancreatic duct was not widened, and no significant abnormalities in FDG uptake were observed.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
The right kidney is enlarged, with an irregular soft tissue density mass measuring approximately 9.4*7.3*9.7cm.
The density is uneven, containing patchy low-density shadows and calcifications.
FDG uptake is unevenly increased (SUVmax=9.5), invading the renal pelvis and calyces.
The boundary with the adjacent diaphragm and right lobe of the liver is indistinct.
The perirenal fascia is thickened.
A soft tissue nodule, approximately 1.0cm in diameter, is present below the right kidney, with unevenly increased FDG uptake (SUVmax=4.2).
The left kidney is normal in shape and size, with punctate dense shadows in the left calyces.
No widening of the renal pelvis, calyces, or ureter is observed.
FDG uptake is not significantly abnormal.
The left adrenal gland is thickened, with no abnormal FDG metabolism.
No significant abnormalities are observed on the right adrenal gland.
The stomach is adequately distended, with slight thickening of the gastric wall in the antrum.
FDG uptake is mildly increased (SUVmax=2.7).
The intestines are not sufficiently full, with a significant amount of residual contents in the intestinal lumen.
No masses were observed in the affected areas.
FDG uptake was increased in some intestinal segments, with an SUVmax of 6.1.
The prostate is full, with punctate dense shadows inside; FDG uptake was not abnormally increased.
The bilateral inguinal canals are widened, containing fatty components.
There is a small amount of hydrocele in the bilateral testicular tunica vaginalis.
The bladder is adequately full, with no obvious positive stones.
Overall bone density is decreased; the spinal alignment is normal, with osteophyte formation at the vertebral margins in some areas and multiple intervertebral disc bulges.
FDG uptake of the entire skeleton is normal.
A small cystic shadow is seen in the left femoral head and neck, with no abnormal FDG uptake.
Focal FDG uptake is present in the left hip periarticular region, with an SUVmax of 6.8 and a long axis of uptake of approximately 1.6 cm.

Impression

1. a. After treatment for right lung cancer, an irregular soft tissue mass with increased FDG metabolism in the upper lobe of the right lung suggests that the tumor is still active. b. Multiple metastases in both lungs. Possible metastases to the right hilar and some mediastinal lymph nodes. c. Emphysema in both lungs. Chronic inflammation and post-inflammatory remnants in both lungs. Bilateral pleural thickening, with a small amount of pleural effusion on the right side. d. Pericardial thickening with effusion. Anemic changes, calcification of some arterial walls (including coronary arteries).

2. a. A mass in the right kidney with increased FDG metabolism, suggestive of malignancy, with the metastasis larger than the primary tumor. b. Metastasis in the right lobe of the liver, with a metastatic lesion below the right kidney. Possible metastasis to the left hip.

3. Cyst in the right lobe of the liver. Calcification in the pancreas.

4. Left kidney stone, left adrenal hyperplasia. Benign prostatic hyperplasia with calcification. Bilateral inguinal hernia. Small amount of hydrocele in both testes.

5. Chronic inflammatory changes in the gastric antrum and part of the intestine.

6. Osteoporosis, degenerative changes in the spine, multiple intervertebral disc bulges. Left femoral head-neck cystic lesion.

7. Low-density thyroid nodules and calcifications with increased FDG metabolism, suggestive of nodular goiter; please combine with ultrasound examination.

8. Age-related brain, deep lacunar infarcts, left cerebellar softening. Right lens poorly visualized; please combine with specialist examination.

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.
